460-86-6 Usage
General Description
1,3-Dibromo-1,1,3,3-tetrafluoropropane is a chemical compound with the molecular formula C3H2Br2F4. It is a colorless, odorless gas and is also known by its trade name Halon 2402. 1,3-DIBROMO-1,1,3,3-TETRAFLUOROPROPANE is primarily used as a fire extinguishing agent, particularly in aircrafts, due to its ability to suppress fires without leaving behind any residue. It is also used in the manufacturing of electronic and semiconductor materials, as well as in certain medical applications. However, 1,3-Dibromo-1,1,3,3-tetrafluoropropane is considered to be an ozone-depleting substance and has been phased out of use in many countries due to its harmful environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 460-86-6 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, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 460-86:
(5*4)+(4*6)+(3*0)+(2*8)+(1*6)=66
66 % 10 = 6
So 460-86-6 is a valid CAS Registry Number.

Polymer chemistry. Part V. γ-Ray induced telomerisation reactions involving 1,1-difluoroethene and hexafluoropropene
Chambers, Richard D.,Proctor, Lee D.,Caporiccio, Gerardo
, p. 241 - 248 (2007/10/02)
Telomerisation reactions have been investigated for the alkenes 1,1-difluoroethene (5) and hexafluoropropene (3) with the telogens CF2Br2 (1), CF3CFBr2 (8) and CF3CBr3 (9), as a means of preparing telomers and co-telomers.The efficiency of chain transfer increases as 1 /= 8 9.Surprinsingly, co-telomerisations of 5 with 3 occurred more efficiently than the corresponding telomerisations with 5 alone.The effects of solvent are described. - Keywords: Telomerisation; γ-Ray induction; 1,1,-Difluoroethene; Hexafluoropropene; NMR spectroscopy; Mass spectrometry
