Check Digit Verification of cas no

The CAS Registry Mumber 104739-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 104739-40:
(8*1)+(7*0)+(6*4)+(5*7)+(4*3)+(3*9)+(2*4)+(1*0)=114
114 % 10 = 4
So 104739-40-4 is a valid CAS Registry Number.

Lactam Acetals: Potential Enamine Synthons in Heterocyclic Synthesis, 1. The Lactam Acetal/Ketene N,O-Acetal System in 1,3-Dipolar Cycloaddition

Moehrle, Hans,Dwuletzki, Heinz

, p. 3591 - 3599 (2007/10/02)

Lactam acetals 1 are transformed to cyclic ketene N,O-acetals 2 and react with 1,3-dipoles.Generally the resulting primary addition compounds which can be detected in some cases stabilize by alcohol elimination and yield amino-substituted condensed hetero
