Looks to me like you arrive and depart from Terminal 2E so it should be no problem, just don't delay.

Also, on the day I looked, there is a 7:10pm CDG-IST that they would put you on if you miss it.

(And if you do miss it, you could hop on a train, have a nice leisurely lunch in Paris and get back in plenty of time.

Either way, I think you're fine.
