Produce a new "rightmost" col to serve as the vlookup's col which contains
the stripped text nums, eg:
In C2, copied down: =RIGHT(B2,4)
where B2 down house the references eg: R1459, etc

Then you could use something like this:
=VLOOKUP(RIGHT(A2,4),C:E,2,0)
where A2 down contains the lookup values, eg: M1459

Above presumes data as you posted is representative
