1,1,2,2,3,3-Hexachloro-1-fluoropropane, also known as HCFC-225, is a chlorofluorocarbon (CFC) derivative that has been used as a refrigerant, blowing agent, and fire extinguishing agent. It is a colorless liquid with a molecular formula of C3Cl6F. 1,1,2,2,3,3-hexachloro-1-fluoro-propane is characterized by its six chlorine atoms and one fluorine atom attached to a propane molecule. Due to its potential to deplete the ozone layer and contribute to global warming, its production and use have been phased out under the Montreal Protocol, an international agreement aimed at protecting the ozone layer.
The CAS Registry Mumber 422-28-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 2 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 422-28: (5*4)+(4*2)+(3*2)+(2*2)+(1*8)=46 46 % 10 = 6 So 422-28-6 is a valid CAS Registry Number.
