Check Digit Verification of cas no

The CAS Registry Mumber 145134-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,3 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 145134-46:
(8*1)+(7*4)+(6*5)+(5*1)+(4*3)+(3*4)+(2*4)+(1*6)=109
109 % 10 = 9
So 145134-46-9 is a valid CAS Registry Number.

Electrocatalyzed Cyanomethylation of Azomethines: A New Synthesis for β-Aminonitriles

Hess, U.,Raasch, A.-K.,Schulze, M.

, p. 487 - 490 (1992)

Certain Schiff-bases (2-7) react in acetonitrile (1) at a Hg-cathode in a new electrocatalyzed cyanomethylation method in good yields without sideproducts to β-aminonitriles (2a-7a).The synthesis is initiated by an electrochemical deprotonation of 1 by azomethine-radical anions in catalytical amount to acetonitril anions (B-).During nucleophilic reaction of B- with 2-7 up to its complete consumption, the cyanomethylation synthon B- is regenerated in a cyclic, self-reproducing process.Quantum chemical calculation in context with cyanomethylation product analysis permit mechanistical insights and exact prediction of suitable azomethines and coupling position for B-.
