Hexachloro-1,1,3,3-tetrafluoro-butane, also known as CCl3CF2CClF2, is a chlorofluorocarbon (CFC) compound that consists of four carbon atoms, six chlorine atoms, and four fluorine atoms. It is a colorless, odorless, and non-toxic gas at room temperature, with a molecular weight of 236.8 g/mol. This chemical is known for its high chemical stability, low toxicity, and excellent dielectric properties, making it suitable for use as a refrigerant, fire extinguishing agent, and foaming agent. 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.
The CAS Registry Mumber 375-38-2 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 5 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 375-38: (5*3)+(4*7)+(3*5)+(2*3)+(1*8)=72 72 % 10 = 2 So 375-38-2 is a valid CAS Registry Number.
