If you actually have the files, you can just use rpm to extract the name
from the rpm file itself:

$ rpm -qp --qf '%{NAME}' some.rpm

This will work even if the rpm file has been renamed to something
completely different.

If you're just working from names, try this:

sed 's/-[^-]*-[^-]*$//' /var/log/rpmpkgs
