Unfortunately that won't work, unless the burning process was interrupted in 
the middle (in which case you wouldn't need to verify anything). This is 
because the files list (TOC - table of contents) is written regardless of 
content beign correctly written (or written at all, for that matter).

You'd better stick with one of the options proposed by Ted Merley. MD5 sum 
would be my personal choice, if you burn a CD from an ISO (which is your 
case).

In another situation, if you want to verify a CD which was burnt on the fly, 
you could use "diff -rq /path/to/dir /media/cdrom" changing paths where 
apropriate.
