The short answer is: You can't.

The longer answer is: When Nero (or any other recording software)
burns files to disc, it creates the ISO data structure in RAM or a
temp file, and then sends that data to the recorder. If you create
another ISO image, you are not guaranteed that the image is bit-by-bit
exactly identical to the first, even if it contains the same files in
the same order. The process of creating the ISO data structure is not
100% predictable, so there is no way to reliably recreate the ISO
image to verify against.

You can, of course, read back all the files and compare them to the
original files.

If you create an ISO file on the hard disk and then burn that, you
might be able to verify the recorded disc against the ISO file. I have
not tried this, nor have I checked if Nero supports it, but it is, at
least, technically possible.
