Check Digit Verification of cas no

The CAS Registry Mumber 68409-00-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,0 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68409-00:
(7*6)+(6*8)+(5*4)+(4*0)+(3*9)+(2*0)+(1*0)=137
137 % 10 = 7
So 68409-00-7 is a valid CAS Registry Number.

Free-Radical Reactions of Fluoroalkanesulfenyl Halides. 4. Reactions of Perfluoroalkane- and Pentafluorobenzenesulfenyl Chlorides with Hydrocarbons in the Presence of Fluorinated Disulfides

Harris, J. F.

, p. 268 - 271 (2007/10/02)

Free-radical reactions of perfluoroalkanesulfenyl chlorides and pentafluorobenzenesulfenyl chloride with cyclohexane and toluene were carried out in the presence of bis(perfluoroalkyl) disulfides and bis(pentaflurophenyl)disulfide to assess the competition between the disulfide and the sulfenyl chloride for reaction with hydrocarbon radicals.With added bis(perfluoroalkyl) disulfides, radical attack occurs only on the sulfenyl chloride, but with added bis(pentafluorophenyl) disulfide, attack occurs on both sulfenyl chloride and disulfide.
