1,1,1,2,3,3-Hexachloro-2,3-difluoropropane, also known as C-94, is a chlorofluorocarbon (CFC) compound with the chemical formula C3Cl6F2. It is a colorless, volatile liquid at room temperature and is highly resistant to chemical reactions. 1,1,1,2,3,3-hexachloro-2,3-difluoro-propane was primarily used as a refrigerant, fire extinguishing agent, and aerosol propellant due to its non-flammable and non-toxic properties. However, it has been identified as a potent ozone-depleting substance, contributing to the depletion of the ozone layer. As a result, its production and use have been phased out under the Montreal Protocol, an international agreement aimed at protecting the ozone layer by reducing the emissions of substances that deplete it.

Check Digit Verification of cas no

The CAS Registry Mumber 1645-71-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1645-71:
(6*1)+(5*6)+(4*4)+(3*5)+(2*7)+(1*1)=82
82 % 10 = 2
So 1645-71-2 is a valid CAS Registry Number.
