Check Digit Verification of cas no

The CAS Registry Mumber 75251-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,5 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75251-31:
(7*7)+(6*5)+(5*2)+(4*5)+(3*1)+(2*3)+(1*1)=119
119 % 10 = 9
So 75251-31-9 is a valid CAS Registry Number.

Azomethines, 1-Azaallyl Anions, and Metastable Secondary Enamines

Knorr, Rudolf,Weiss, Alfons,Loew, Peter,Raepple, Edith

, p. 2462 - 2489 (2007/10/02)

E/Z equilibrium constants of the ketone anils 6a-s do not depend significantly on the inductive substituent effect. 1H NMR chemical shifts used for configurational classification are also effective for assignments in comparable, isomerically almost pure azomethines 6aa-pp and may be explained by the anisotropic shift model.The 1-azaallyl anions 7 prepared by deprotonation are characterized by 1H NMR spectroscopy.Kinetic and thermodynamic control of this metallation reaction result in different preferential configurations of such anions, the methanolysis of which yields metastable sec. enamines 8 by regio- and stereospecific N-protonation.It is possible to estimate further substituent parameters λd from E/Z equilibria.
