Check Digit Verification of cas no

The CAS Registry Mumber 1219705-54-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,7,0 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1219705-54:
(9*1)+(8*2)+(7*1)+(6*9)+(5*7)+(4*0)+(3*5)+(2*5)+(1*4)=150
150 % 10 = 0
So 1219705-54-0 is a valid CAS Registry Number.

Applications of allylsamarium bromide as a grignard reagent and a singleelectron transfer reagent in the one-pot synthesis of dienes and trienes

Hu, Yuanyuan,Zhao, Tao,Zhang, Songlin

supporting information; experimental part, p. 1697 - 1705 (2010/06/17)

The utility of allylsamarium bromide, both as a nucleophilic reagent and a single-electron transfer (SET) reagent in the reaction of α-halo, γ-halo-αβ-unsaturated ketones and esters with allylsamarium bromide is reported for the first time in this paper. From a synthetic point of view, a general, efficient and experimentally simple one-pot method for the preparation of 1,4-dienes and trienes is developed. A possible mechanism of the transformation is proposed.
