There are many MD5 hash checkers available on the web.  Some are GUI based and others are command line driven. They are available for all Operating Systems.  As long as it uses the MD5 algorithm, any program should work.

Here is the link to an open-source Windows MD5 checking program:
http://md5deep.sourceforge.net/
Once you have installed it, use the md5deep.exe to calculate the hash - example - md5deep.exe HS_CD1_2014_APRIL30.iso
You can then compare that string with the one provided above.

Most programs like md5keep even allow you to check one or more MD5 hash strings from a file containing known hashes.  Check out the MD5DEEP.txt file for more information.
