While there is nothing wrong with Gary's answer, here is alternatives
=MOD(A1,10) will return the last digit of the number in A1

Hi all,

I am trying to have excel determine what the last digit is in a 9 digit
series of numbers to apply basic encryption to said series of 9 digit
numbers.

Is there a way that Excel can recognize whether the last digit is a 1 or
2,
etc...

Thanks for any help you can give me.
