1,2,2-trichloro-3,3-difluoro-butane is a chlorofluorocarbon (CFC) with the chemical formula C4H2Cl3F2. It is a colorless, volatile liquid at room temperature and is known for its high chemical stability. 1,2,2-trichloro-3,3-difluoro-butane was historically used as a refrigerant and as a propellant in aerosol products due to its ability to absorb and release heat efficiently. However, it is also a potent greenhouse gas and contributes to the depletion of the ozone layer, which is why its production and use have been phased out under the Montreal Protocol to protect the environment. The compound's molecular structure features three chlorine atoms and two fluorine atoms, which are the primary reasons for its environmental impact.
The CAS Registry Mumber 374-24-3 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 4 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 374-24: (5*3)+(4*7)+(3*4)+(2*2)+(1*4)=63 63 % 10 = 3 So 374-24-3 is a valid CAS Registry Number.
