Your problem description is a bit underspecified... Given what is provided:
=ISNUMBER(MATCH(RIGHT(C2,2)+0,$K$2:$K$10,0))+
if the items in K2:K10 are numbers. Otherwise:
=ISNUMBER(MATCH(RIGHT(C2,2),$K$2:$K$10,0))+0
Regarding the single digit cases...
=ISNUMBER(MATCH(RIGHT("0"&C2,2),$K2:$K&10,0))+0
assuming that K2:K10 does not house true numbers.
