Skymetric motioncam key

Downloaded this software called Motioncam which lets you use your mobile camera as a security camera. When I went to purchase it on their website at skymetric.com it turns out the site's already dead.

So I used the Cavaj java decompiler to get into the class files and figure out the auth mechanism. It's very simple - just plug the following formula into an excel spreadsheet (in any col except A1) . Then in A1 put the Activation key that the software gives you when you click Activate.

=INT((17 * A1 + 90001) / 7 + MOD(11 * A1 + 9001, 19) + 5 * A1 + 911)
