Check Digit Verification of cas no

The CAS Registry Mumber 137658-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,5 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137658-81:
(8*1)+(7*3)+(6*7)+(5*6)+(4*5)+(3*8)+(2*8)+(1*1)=162
162 % 10 = 2
So 137658-81-2 is a valid CAS Registry Number.

Dual role of allylsamarium bromide as a Grignard reagent and a single electron transfer reagent in the one-pot synthesis of terminal olefins

Li, Ying,Hu, Yuan-Yuan,Zhang, Song-Lin

, p. 10635 - 10637 (2013)

The utility of allylsamarium bromide, both as a nucleophilic reagent and a single-electron transfer reagent, in the reaction of carbonyl compounds with allylsamarium bromide in the presence of diethyl phosphate is reported in this communication. From a synthetic point of view, a simple one-pot method for the preparation of terminal olefins is developed.
