Regex to replace numbers in a string

Hi,

I'd like to remove any number of digits within a string only if the appear at the end of the string. Say that I have strings such as:

Strings
---------------------------
123ABC666
ABC123456
55ABCDE23423423423423423423423FG
FFF12092184928903489238492384982394

Desired output
--------------------------
123ABC
ABC
55ABCDE23423423423423423423423FG
FFF

I can detect if there are numbers at the end of the string using "\d$", and I can replace with $string -replace "[0-9]". However, this wipes out any other numbers anywhere in the string....what I want to do is only wipe out numbers at the end of the string.

if($string -match "\d$") {
     $string -replace "[0-9]"  # Need to target ONLY numbers at the end of string
} else {
     $string
}
