I think you expect rename -> prename as is the case on Debian. Another one with prename:
Code:
prename -n 's/^(CMRLPCR\d{6})_[^_]*/$1/' *.bum

Or
Code:
prename -n 's/_[^_]*//' CMRLPCR??????_*.bum

The rename from util-linux is much different, and IMHO cannot have references like $1 $2 that refer to (group1) (group2).
The only portable solution is a loop.
