1-Fluoroxy 2-chlorotetrafluoroethane, also known as C2ClF5O, is a chlorofluorocarbon (CFC) compound that consists of two carbon atoms, five fluorine atoms, one chlorine atom, and one oxygen atom. It is a colorless, volatile, and non-toxic liquid at room temperature. This chemical is primarily used as a refrigerant, aerosol propellant, and solvent in various industrial applications. 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 2203-54-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 3 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2203-54: (6*2)+(5*2)+(4*0)+(3*3)+(2*5)+(1*4)=45 45 % 10 = 5 So 2203-54-5 is a valid CAS Registry Number.
