1,2,2,3,3,4-Hexachloro-1,1,4,4-tetrafluoro-butane, also known as C-94, is a chlorofluorocarbon (CFC) compound with the chemical formula C4Cl6F4. It is a colorless, odorless, and non-toxic liquid at room temperature. 1,2,2,3,3,4-hexachloro-1,1,4,4-tetrafluoro-butane is a derivative of butane, where four hydrogen atoms are replaced by fluorine atoms, and two hydrogen atoms are replaced by chlorine atoms. Due to its chemical structure, it has been used as a refrigerant, a propellant in aerosol products, and as a cleaning agent in various industrial applications. However, its production and use have been phased out globally under the Montreal Protocol due to its potential to deplete the ozone layer and contribute to global warming. The compound's stability and resistance to degradation make it a persistent environmental pollutant, which can lead to long-term environmental impacts.
The CAS Registry Mumber 375-33-7 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 3 respectively. Calculate Digit Verification of CAS Registry Number 375-33: (5*3)+(4*7)+(3*5)+(2*3)+(1*3)=67 67 % 10 = 7 So 375-33-7 is a valid CAS Registry Number.
