How can I determine CD Serial Number before I burnt it

[qawsed]

Yes, I know I know.
of course. Someone will copy it sooner or later. But no everyone.
I'm selling my programs to inexperienced users, in general.
Almost everybody have CD-Writer at their home or office.
The copy process is to easy for even a child.
Copy has to be hard a little.
A lot of poeple that I know, don't struggle for copy a CD.
