Can you add a validation for supplier tax registration number based on a prefix?

Summary: Our client requires a validation for supplier tax registration number that checks if 2 registration numbers for 2 different supplier names match, while one has a prefix of 0 and the other does not.

Content (required):

For example, If a supplier name 'Tel Aviv - University' with Tax Registration number 1234 exists, and a user tries to create(or register) a new supplier with name 'University - Tel Aviv' with Tax Registration number 01234, the system should match between the two registration numbers, while ignoring the prefix of 0, and prevent the user from creating the latter.

Is there some sort of functionality that exists in the system?
