Use array of possible values in a NON array if formula

[drom]

Hi and thanks in advance!

I have a column with strings.
This strings may en with values such as:

"1"
"2"
"3"
"4"
"5"​

I need a formula to let me know if ig any of this values is meet
I do not want to use Countif, because this eg is gonna be used in a bigger nested formula

I need some thing like
=IF(RIGHT(A2;1)={"1";"2";"3";"4";"5"};"OK";"Wrong")


My problem comes because:

If A1 end in 1, eg: "France1" I get "OK"
If A5 end in 2, eg: "Italy2" I get "Wrong"

and for this 2nd eg, I need "OK"​

ps:
I Can't use

5 IFS
one other column
Vlookups​

This is why I am trying to correct
=IF(RIGHT(A2;1)={"1";"2";"3";"4";"5"};"OK";"Wrong")

DONE
=IF(MATCH(RIGHT(A1;1);{"1";"2";"3";"4";"5"};0);"OK";"Wrong")

Or, added a OR() in the logical test

=IF(OR(RIGHT(A2;1)={"1";"2";"3";"4";"5"});"OK";"Wrong")
