354-53-0 Usage
General Description
1-Bromo-2-chlorotetrafluoroethane is a chemical compound with the molecular formula C2HClBrF4. It is a colorless, nonflammable gas that is primarily used as a refrigerant and propellant in aerosol products. 1-BROMO-2-CHLOROTETRAFLUOROETHANE is considered a chlorofluorocarbon (CFC) and is known for its ozone-depleting properties. Due to its potential harm to the environment, the production and use of 1-bromo-2-chlorotetrafluoroethane have been restricted under the Montreal Protocol and other international agreements aimed at protecting the ozone layer. As a result, alternative compounds with lower ozone depletion potential are now being used in its place. Despite its restricted use, 1-bromo-2-chlorotetrafluoroethane is still present in some older refrigeration and air conditioning systems.
Check Digit Verification of cas no
The CAS Registry Mumber 354-53-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 354-53:
(5*3)+(4*5)+(3*4)+(2*5)+(1*3)=60
60 % 10 = 0
So 354-53-0 is a valid CAS Registry Number.

The reaction of perfluoroalkanesulfinates, RfCF2SO2Na, with allyl and propargyl halides, in the presence of (NH4)2S2O8, gave 3-(perfluoroalkyl)prop-1-enes (RfCH2CH=CH2) and 3-(perfluoroalkyl)allenes (RfCH=C=CH2), respectively, in good yield.Evidence is presented for a radical addition-elimination mechanism for the reaction.The reaction represents a synthetically viable and convenient route to such compounds.
