The command is md5sum and is quite common; forget which utility
package includes but is pretty basic I think.  You would type for
md5sum  slackware-10.0-install-d1.iso.md5
The output will eventually come up saying the name of the file and if
it is ok or not.

Create a mount point like '/mnt/iso'.  Then use the following mount
mount -t iso9660 -o loop slackware-10.0-install-d1.iso /mnt/iso
That should hang your ISO image on the loop device for you.  You need
to have loopback support in your kernel.
Then you can cd into /mnt/iso and start shopping!:)
