Company Formation with .com as part of the name ?

Hi All,
Was wondering if this is the right section to post my query
I am planning to register a company ( pvt ltd ) with the name ending with .com and it would be a Realty company and we want it to be ABCRealty.Com Pvt. Ltd.
My query is does ROC allow registration of such a name with the name ending with .com or do i have to register with ABCRealty Com Pvt. Ltd without the .
Thanks in advance for the help
Regards
Ram
