1,2,3,4,5,6-Hexachloro-1,2,4,5-tetrafluoro-cyclohexane, also known as C6Cl6F4, is a chlorofluorocarbon (CFC) compound with a cyclic structure. It consists of a six-carbon ring with four fluorine atoms and six chlorine atoms, making it a highly chlorinated and fluorinated molecule. This chemical is known for its stability, non-flammability, and low reactivity, which are characteristics that made 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 and public health.
The CAS Registry Mumber 377-69-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 7 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 377-69: (5*3)+(4*7)+(3*7)+(2*6)+(1*9)=85 85 % 10 = 5 So 377-69-5 is a valid CAS Registry Number.
