How can I check if a new copy of Coreldraw X5 has been been used?

I've been going through my Dad's things, and found a copy of Corel Draw X5 that I am fairly certain hasn't been registered. 

If it hasn't, I would like to sell it - but how do I find out whether it has been previously registered or not? 

Thanks for any suggestions.
