How can I obtain product key for Adobe cs3

Hello,

I purchased Adobe Design Suite CS3 A couple years ag when it forst came out and my PC was ruined in a flood, I managed to salvage most of my software CD's but the packaging is ruined and the product key is unreadable, Adobe says the need my phone # or Email address to verify from product registration Well a long story short My EX wife originally installed the software and they seem to be unable to find any registrations under either her name maiden name or any of our past phone numbers. Is there any way to get the product key off the cd itself?
