Sorry, but this is incorrect. 1C37 designates base model Chevelle, but it does not by itself designate a Heavy Chevy. It is true that every Heavy Chevy in 1972 will have a VIN that begins with 1C37, but so do all the base model Chevelle coupes in 1972. So the VIN by itself in 1972 will not verify that it is a Heavy Chevy.
This has been discussed at length at Team Chevelle, and Dale McIntosh has the VIN breakdowns of all models at his site.

And here is 1972 Heavy Chevy specific info:

And a direct quote from the site:
" Just the fact you have a 1C37 Chevelle Sport Coupe does not automatically make it a Heavy Chevy anymore that the fact you have a 13637 Malibu Sport Coupe make it a Z15 SS-optioned Malibu."
