Dear Jao, AIIMS final registration has no correction window. Once you click on 'Next' and make the payment, what you have entered there, stays there. There is no way to correct the errors in the final regustration process. Sorry to disappoint you but you cannot make any changes to your Roll number that has been entered wrong.
