Apart from a basic string search, this is incorrect.  Allowable letters at the end only A-D.
As before, avoid

This should not be used to make any proper NINO validation.  None of the requirements have been met bar a very basic layout.  For instance, where is the check that the last char should be only chars A-D?  Avoid.
