1,1,2,2,3-Pentachloro-1,3,3-trifluoropropane is a chlorofluorocarbon (CFC) with the chemical formula C3Cl5F3. It is a colorless, volatile liquid at room temperature and is known for its high stability and low reactivity. 1,1,2,2,3-pentachloro-1,3,3-trifluoro-propane was once used as a refrigerant and as a propellant in aerosol products due to its ability to absorb and release heat without undergoing significant chemical change. However, it is now recognized as a potent greenhouse gas and has been implicated in the depletion of the ozone layer. As a result, its production and use have been phased out under the Montreal Protocol to protect the environment and mitigate climate change.
The CAS Registry Mumber 1599-43-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,9 and 9 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1599-43: (6*1)+(5*5)+(4*9)+(3*9)+(2*4)+(1*3)=105 105 % 10 = 5 So 1599-43-5 is a valid CAS Registry Number.
