6 digit Clydesdale account numbers fail modulus check

Problem

Bank Wizard returns the modulus check failed error for 6 digit Clydesdale account numbers.

Cause

Historically, you could use 6 digit account numbers, which Clydesdale then transposed to an 8 digit account number.
 
However, Clydesdale have informed us that customers should now use the full 8 digit account number. This is the last 8 digits of their bank card number.
