Reading the structure
The structure 1!a5!n5!n12!c describes everything after the
country code and check digits. Each group is a length followed by a character type:
n means digits only, a means uppercase letters only, and
c means letters or digits. An exclamation mark means the length is fixed.
This matters when you are typing an IBAN by hand: in a group marked n, a letter O where a zero belongs is a structural error the checker will report, not a checksum failure.
