Check Digit Verification of cas no

The CAS Registry Mumber 1392402-62-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,4,0 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1392402-62:
(9*1)+(8*3)+(7*9)+(6*2)+(5*4)+(4*0)+(3*2)+(2*6)+(1*2)=148
148 % 10 = 8
So 1392402-62-8 is a valid CAS Registry Number.

DMSO-catalyzed chlorination of alcohols using N-phenylbenzimidoyl chloride

Wang, Qiang,Xu, Jian,Xu, Zhou-Qing,Yan, Ji-Dan

, p. 2071 - 2076 (2013)

N-phenylbenzimidoyl chloride has been demonstrated as an efficient chlorination reagent catalyzed by dimethyl sulfoxide (DMSO) in conversion of alcohols to corresponding chlorides. The reaction conditions were mild, and most of the substrates gave satisfactory yields. The configuration inversion of the chlorination was proved using optically active phenyl alcohols. The amount of DMSO can be as low as 0.001 eq without reducing the efficiency of the chlorination. A plausible mechanism for the reaction was proposed and proved by experiments. The reaction is stereoselective and potentially chemoselective among primary benzyl alcohols, secondary benzyl alcohols, and unactivated aliphatic alcohols.
