Check Digit Verification of cas no

The CAS Registry Mumber 1021452-36-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,4,5 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1021452-36:
(9*1)+(8*0)+(7*2)+(6*1)+(5*4)+(4*5)+(3*2)+(2*3)+(1*6)=87
87 % 10 = 7
So 1021452-36-7 is a valid CAS Registry Number.

Synthesis of aryl glycines by the α arylation of weinreb amides

Hirner, Sebastian,Panknin, Olaf,Edefuhr, Magnus,Somfai, Peter

, p. 1907 - 1909 (2008/12/22)

(Chemical Equation Presented) A rare example of the umpolung of an enolate forms the basis of the title reaction. In this procedure, a Grignard reagent is added to the iminium ion formed from the Weinreb amide upon treatment with a base (see scheme). When a chiral amide was used as the starting material, the nucleophilic addition proceeded with high diastereoselectivity. LDA = lithium diisopropylamide.
