Here's the physical CD side of the equation:

   dd if=/dev/cdrom | md5sum

If you want to script it (in a bash script), here's an example:

   if [ `dd if=/dev/cdrom | md5sum` != `md5sum %1.iso` ]; then
      echo "Bad CD"
      echo "Good CD"

Where the first parameter is the ISO image file (e.g., if it was named
"cdmd5sum", "cdmd5sum blah.iso")
