public final class IBANValidator extends Object implements javax.validation.ConstraintValidator<IBAN,CharSequence>
This routine is based on the ISO 7064 Mod 97,10 check digit caluclation routine.
The two check digit characters in a IBAN number are the third and fourth characters
in the code. For check digit calculation/validation the first four characters are moved
to the end of the code.
So CCDDnnnnnnn
becomes nnnnnnnCCDD
(where
CC
is the country code and DD
is the check digit). For
check digit calcualtion the check digit value should be set to zero (i.e.
CC00nnnnnnn
in this example.
For further information see Wikipedia - IBAN number.
