[jira] [Created] (VALIDATOR-330) IbanCheckDigit.isValid() returns True for some invalid IBANs

[Peter Shawe (JIRA)]

Peter Shawe created VALIDATOR-330:
-------------------------------------

             Summary: IbanCheckDigit.isValid() returns True for some invalid 
IBANs
                 Key: VALIDATOR-330
                 URL: https://issues.apache.org/jira/browse/VALIDATOR-330
             Project: Commons Validator
          Issue Type: Bug
          Components: Routines
    Affects Versions: 1.4.0 Release
            Reporter: Peter Shawe


For example, isValid() returns True for both of these IBANs; 
"IE01AIBK93118702569045" and "IE98AIBK93118702569045".  The "IE98" version is 
the correct one (confirmed with online checkers, which also fail the "IE01" 
version).

calculate() correctly returns "98".  As a workaround I'm calling calculate() 
and comparing the result with the checksum in the original IBAN.
