Check Digit Verification of cas no

The CAS Registry Mumber 22434-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,3 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22434-45:
(7*2)+(6*2)+(5*4)+(4*3)+(3*4)+(2*4)+(1*5)=83
83 % 10 = 3
So 22434-45-3 is a valid CAS Registry Number.

Approche de la syntese d'α-aminonitriles en milieu organique anhydre

Geneste, Patrick,Kamenka, Jean-Marc,Dessapt, Patrice

, p. 187 - 191 (2007/10/02)

A Strecker-like reaction in organic medium gives two isomeric α-aminonitriles in good yield.The influence of water and temperature on the isomeric ratio is discussed.Under quasi-kinetic conditions (anhydrous medium) the isomeric ratio is 60 40 minimum in favour of the non-thermodynamic product.If the imonium ion is the intermediate, there is preferential equatorial nucleophile attack rather than axial.
