Strip leading and numbers from a string.

Hello I have two vars loaded with
$VAR1="ISOMETHING103"
$VAR2="COTHERTHING04"

I need to:
1) Strip the first char. Could be sed 's/^.//'
2) The number has it's rules. If it has "hundreds", it needs to be striped.
If it is just two digits it shouldn't.
So, for VAR1 output should be "SOMETHING03".
And for VAR2 output should be "OTHERTHING04".
My main issue here is how can I strip the "hundreds"?
Input would be all caps always.

Thanks in advance,
Sebastian
