Conditional formatting based on the formula

I've attached a workbook with explanation inside there,

Main Goal is to do conditional formatting on the A & B columns.

Here is a formula based on Cell A:
=IF(RIGHT(A1,5)="396OL","101OL",IF(RIGHT(A1,5)="400OL","101OL",IF(RIGHT(A1,5)="413OL","103OL",RIGHT(A1,5))))

Thank you
