      "description": "Validates a Brazilian bank account (bank code, agency, account and check digit).\n\n- `bankCode`, `agency` and `account` have every non-digit character removed (`\"1-584\"` and `\"0021.0169\"` are read as digits). `digit` is uppercased and keeps only digits, `P` and `X`. A value that is not an object, or a field that is not a string, makes the account invalid.\n- `params` carries `bankCode` (3 digits), `agency` (1 to 5 digits), `account` (1 to 13 digits) and `digit` (1 or 2 characters, or `X` for Banco do Brasil and `P` for Bradesco), all strings.\n- `bankCode` must be a Banco Central STR participant (the list that `bank.getByCode` uses). The function rejects any other code.\n- Nine banks are checked with a check-digit rule, each with its own agency and account lengths (`digit` is one character):\n  - Banco do Brasil (001): agency 4 to 5 digits, account 8 to 10 digits. Modulus 11 over the account, weights 2 to 9 cycling from the right; a result of 10 gives `X`.\n  - Santander (033): agency 4 digits, account 8 digits. Over agency + `00` + account, weights `9,7,3,1,0,0,9,7,1,3,1,9,7,3`, keeping only the units digit of each product; the digit is (10 - sum mod 10) mod 10.\n  - Banrisul (041): agency 4 digits, account 9 digits (tipo 2 digits + conta 7 digits). Weights `3,2,4,7,6,5,4,3,2` over the account, modulus 11; remainder 0 gives `0`, remainder 1 gives `6`, otherwise 11 minus the remainder.\n  - Caixa (104): agency 4 digits, account 11 or 12 digits. See below.\n  - Bradesco (237): agency 4 digits, account 7 digits. Modulus 11 over the account, weights 2 to 7 cycling from the right; a result of 10 gives `P`.\n  - Nubank (260): agency 4 digits, account 5 to 13 digits. Verhoeff digit over the account with leading zeros dropped.\n  - Itaú (341): agency 4 digits, account 5 digits. Modulus 10 over agency + account.\n  - HSBC/Kirton (399): agency 4 digits, account 6 digits. Weights `8,9,2,3,4,5,6,7,8,9` over agency + account, modulus 11; remainder 10 gives `0`.\n  - Citibank (745): agency 4 digits, account 10 digits. Weights `11,10,9,8,7,6,5,4,3,2` over the account, modulus 11; remainder 0 or 1 gives `0`, otherwise 11 minus the remainder.\n- No act of the Banco Central, of another government body or of FEBRABAN sets these rules. The FEBRABAN CNAB 240 layout (v11.0, notes G009 to G012) calls each check digit a \"código adotado pelo Banco\" and gives no algorithm.\n- Official source (the bank's own layout manual): Caixa (both digits, CNAB 400 notes NE051/NE052 and CNAB 240 note G011), Santander (the account digit, Débito Automático 150 positions v08, April 2026) and Banco do Brasil (the agency digit, Doc5175 Anexo XI; the manual only calls the account digit \"módulo 11\", which matches the rule here). The rules here match their worked examples.\n- Third-party compendium: the other rules (Banrisul, Bradesco, Itaú, HSBC/Kirton, Citibank and the Caixa 11-digit form) follow the Icatu Seguros compendium \"Regras de Validação de dígito verificador de agência e conta corrente\", a private compilation. Nubank publishes no rule; its Verhoeff digit comes from open-source validators that derived it from real accounts.\n- Caixa (104): the agency has 4 digits and the digit is 1 character. A 12-digit account (the \"sem operação\" form of the Caixa layouts) accepts either of the two Caixa digits: the account digit over the 12 digits (official example: 000000109990 gives 6) or the agency/account digit (0161 + 000000109990 gives 5). Both are modulus 11 with weights 2 to 9 from the right, a result above 9 giving 0. The older 11-digit form, operação (3 digits) + conta (8 digits), keeps the compendium's agency/account rule. 2.4.0 rejected a 12-digit Caixa account.\n- These banks are checked by structure only, because no check-digit rule of theirs is known: Inter (077), Ailos (085), XP (102), Unicred (136), Stone (197), BTG Pactual (208), Original (212), PagBank (290), BMG (318), Mercado Pago (323), C6 (336), PicPay (380), Cora (403), Pan (623), BV (655), Daycoval (707), Sicredi (748) and Sicoob (756). Agency (1 to 5 digits) and account (1 to 13 digits) only need to fit their lengths, and a single numeric `digit` is enough (`X` and `P` are not accepted).\n- Every other listed bank uses a generic fallback: a 1-character `digit` must equal the mod 10, the boleto mod 11 or the bank mod 11 of the account, so up to three of the ten digits pass for a given account. A 2-character digit chains mod 10 then mod 11. No published rule backs the fallback: `true` for a bank outside the lists above says the structure is plausible, not that the check digit is proven.\n- For Banco do Brasil the agency digit is not checked. A 5-digit agency (`1584-9`) is only held to the length, whatever its last digit is.",
