About the Czech Republic IBAN
An IBAN (International Bank Account Number) for Czech Republic has 24 characters: the country code CZ, a 2-digit check number, a 4-character bank code and the account number. The check digits are calculated with the ISO 7064 MOD-97 algorithm, so a single typo makes the IBAN invalid — which is what this tool checks.
