IBAN Validator

Paste any International Bank Account Number (IBAN) and verify it: the country prefix is matched against the ISO 13616 registry (~80 countries), the length is checked against the spec for that country, and the MOD-97 checksum is computed digit-by-digit using big-integer chunked arithmetic. The bank code and account number are extracted per the country's BBAN layout. Useful for finance teams verifying invoices, backend engineers wiring up SEPA payouts, and customer-support agents triaging failed transfers.
