1,1-dichloro-1-fluoro-butane, also known as 1,1-dichlorobutane-1-fluoride, is an organic compound with the chemical formula C4H7Cl2F. It is a colorless liquid with a chloroform-like odor and is used as a refrigerant, blowing agent, and solvent. 1,1-dichloro-1-fluoro-butane is characterized by its two chlorine atoms and one fluorine atom attached to the same carbon atom, which contributes to its unique properties. It is synthesized through the reaction of 1,1-dichlorobutane with hydrofluoric acid. Due to its potential environmental impact, particularly its contribution to ozone depletion, its use is regulated under the Montreal Protocol.
The CAS Registry Mumber 460-28-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 0 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 460-28: (5*4)+(4*6)+(3*0)+(2*2)+(1*8)=56 56 % 10 = 6 So 460-28-6 is a valid CAS Registry Number.
