Then another nine digit number, $q$ is formed by concatenating $r$ and the next $7$ digits of the number. docs class IBAN(Base): '''The IBAN object. The mod of this number with respect to $97$, $r$ is obtained. Validate the entire IBAN using MOD 97 operaationas decribed by ISO-7064. Validate the structure of BBAN for the specific country.

Validate the IBAN string size for the specific country. If the modulus is $1$, then it's a valid IBAN number. The modulus of the hence obtained number, let's say $x$, with respect to $97$ is checked. The first four characters of the IBAN number are pulled out from the beginning and are appended at the end of the string.Īll the letters in the hence obtained string of characters are replaced by the ASCII value of their corresponding uppercase letter decreased by $55$.
