I have been able to locate the persons who are nominally in charge of the MCA-21 project from the invitation to the seminar.
Person responsible for MCA-21 in Maharashtra :
Mr. V S Rao, Regional Director - Western Region Ministry of Company Affaires
Mr. Vijayan Menon Registrar of Companies
TCS representative : Mr. Sohel Bogani, Regional Head - Business Development
Unfortunately, I do not have their email id or phone nos. However, they should be listed in the government departmental directories in www.nic.in
