R12 Bank validation

We are still underway with our R12 development and have discovered when we create an account for in France, Oracle is not requiring a check digit in the bank account window. No validation seems to be taking place on any of the mandatory fields according to what the cash manager's user guide states. Is this something you need to turn of for validations to process when creating banks, branches and accounts? I don't see any mention of a required step in the CM user guide to turn on validations.

Thank you.
