Ca final registration details lost

I cleared my CA Foundation and CA Inter a long time back. Took admission in CA Final and was allotted an NRO number. I attempted Finals once in 2001 and left it. Now, I am thinking about attempting again but I have lost my Final registration details as well as NRO number. Is there any way I can retrieve that? Also, what do I have to do in order to be eligible for new scheme Finals. I finished my Articles back in 2001. Thanks
