Hexachloro-3,3-difluoro-penta-1,4-diene is a chlorofluorocarbon (CFC) with the chemical formula C5Cl6F2. It is a colorless, volatile liquid at room temperature and is known for its high chemical stability. hexachloro-3,3-difluoro-penta-1,4-diene was historically used as a refrigerant and as a propellant in aerosol products due to its ability to absorb and release heat without undergoing a phase change. However, it is also a potent greenhouse gas and contributes to the depletion of the ozone layer, which led to its phase-out under the Montreal Protocol due to its environmental impact. The compound's structure features a pentadiene backbone with three chlorine atoms on each of the terminal carbons and two fluorine atoms on the central carbon, which gives it its unique properties.
The CAS Registry Mumber 3231-51-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,3 and 1 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3231-51: (6*3)+(5*2)+(4*3)+(3*1)+(2*5)+(1*1)=54 54 % 10 = 4 So 3231-51-4 is a valid CAS Registry Number.
