Given the expected output and your requirement that the last character should be dropped, the outputs dont match.
34567 vs ASD34567

Is it always the first 3 characters and the last or you want the alphabets alone to be dropped ?

You can start with this

Code:
output1=$(echo $input | sed -e "s/^...\(.*\).$/\1/g")
