After a lot of searching and information I decided to travel from Delhi to Grand Cayman. I am thinking of two separate ticket booking:

1. Delhi (Del) to Moscow(Svo) 5:10 Am - 9:20 Am Aeroflot. Layover 2:40 Hours
2. Moscow(Svo) to Havana(Hav).12:00 Pm - 5:15 Pm Aeroflot.
3. Havana - Gcm after 22 Hours.

I want to Know about the checked in luggage. Will it directly reach Havana or I have to collect it at Moscow airport?

I will not be requiring any visa to transit at Moscow or Havana.
