I am sorry but I have no idea how to read the checksum from a cd/dvd if thats possible. The easiest way to check the md5sum for the iso is to open the file manager and navigate into the directory where it was downloaded, if you still have it, and right click on the .iso file and go down the list to "Check Md5sum" click it and when it finishes it will display a string of numbers and letters. Check this string against the md5 checksum available on the page you downloaded the iso from. If every thing matches the download is ok, if not you should download the iso again. I usually use a download manager that has md5 checking built in and put the string in so it can be checked after the download completes without me having to do anything extra. One such download manager is an add-on for firefox called "down them all" it is the one I use, but you may find others.
