Propane, 1,1,2,3,3-pentachloro-1,3-difluoro- is a chlorofluorocarbon (CFC) with the chemical formula C3H2Cl5F2. It is a colorless, volatile liquid at room temperature and is a derivative of propane, where five chlorine atoms and two fluorine atoms replace hydrogen atoms in the molecule. Propane, 1,1,2,3,3-pentachloro-1,3-difluoro- is known for its high stability and low reactivity, which makes it useful in various industrial applications such as refrigerants, aerosol propellants, and solvents. However, 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 to protect the environment.
The CAS Registry Mumber 431-82-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 1 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 431-82: (5*4)+(4*3)+(3*1)+(2*8)+(1*2)=53 53 % 10 = 3 So 431-82-3 is a valid CAS Registry Number.
