Check Digit Verification of cas no

The CAS Registry Mumber 691383-39-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,3,8 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 691383-39:
(8*6)+(7*9)+(6*1)+(5*3)+(4*8)+(3*3)+(2*3)+(1*9)=188
188 % 10 = 8
So 691383-39-8 is a valid CAS Registry Number.

Unexpected regiospecific reduction of the double bond by NaBH4 in 2-(1-methyl/1H-benzimidazole-2-yl)-3-aryl-acrylonitrile

Dubey,Reddy, P. V. V. Prasada

, p. 2259 - 2266 (2008/02/07)

Condensation of (1H-benzimidazole-2-yl)-acetonitrile 1 with aromatic aldehydes in 5% NaOH solution gave the corresponding 2-(1H-benzimidazole-2-yl)- 3-aryl-acrylonitrile 2, which on treatment with NaBH4 in ethanol unexpectedly gave 2-(1H-benzimidazole-2-yl)-3-aryl-propionitrile 3 by the regiospecific reduction of the double bond. Shaking a solution of 2 with H2/Pd-C in methanol also gave 3. Reaction of 2 with DMS gave the corresponding N-methylated analogue 5, which also with NaBH4 gave 6, once again by the regiospecific reduction of the double bond as in the case of 1-demethylated analogue (i.e., 2).
