You're almost there.  Run 
	# md5sum -c /path/to/MD5SUMS >> /root/cachesums.txt

Now, /root/cachesums.txt will have the results.  Files that checked OK
will have "OK" in the line along with the file name.  Files that exist
and failed will (I think) have a FAILED (you can manually look and see
for sure), while files that did not exist will have a suitable error
message listed.

Now you can use grep on the cachesums.txt file, searching for lines that
say OK so you know what is safe to use, and searching for FAILED so you
know what are corrupted (if any).  You can ignore the not-found error
