Check Digit Verification of cas no

The CAS Registry Mumber 140479-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,7 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140479-90:
(8*1)+(7*4)+(6*0)+(5*4)+(4*7)+(3*9)+(2*9)+(1*0)=129
129 % 10 = 9
So 140479-90-9 is a valid CAS Registry Number.

The Invention of Radical Reactions. Part XXI. Simple Methods for the Radical Deoxygenation of Primary Alcohols.

Barton, Derek H. R.,Blundell, Paul,Dorchak, Joseph,Jang, Doo Ok,Jaszberenyi, Joseph Cs.

, p. 8969 - 8984 (2007/10/02)

Novel radical-chain deoxygenations of primary alcohols are described.The alcohols are acylated with the reagents pentafluorophenyl chlorothionoformate, 2,4,6-trichlorophenyl chlorothionoformate and 4-fluorophenyl chlorothionoformate and the intermediate thionocarbonates are deoxygenated with tributyltin hydride, triphenylsilane, diphenylsilane or phenylsilane in high-yielding reactions.Key Words: Thionocarbonates, Tributyltin hydride, Triphenylsilane, Diphenylsilane, Phenylsilane, Radical deoxygenations.
