Check Digit Verification of cas no

The CAS Registry Mumber 78837-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,3 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78837-63:
(7*7)+(6*8)+(5*8)+(4*3)+(3*7)+(2*6)+(1*3)=185
185 % 10 = 5
So 78837-63-5 is a valid CAS Registry Number.

Amidoselenation of Olefins and Its Utilization for Synthesis of Allylic Amides

Toshimitsu, Akio,Aoai, Toshiaki,Owada, Hiroto,Uemura, Sakae,Okano, Masaya

, p. 4727 - 4733 (2007/10/02)

The reaction of phenylselenyl chloride with olefins in acetonitrile containing trifluoromethanesulfonic acid and water affords β-acetamidoalkyl phenyl selenides in good to excellent yields.This represents the first example of one-pot amidoselenation of mono- and disubstituted olefins.The reaction can be carried out in benzonitrile, propionitrile, butyronitrile, or ethyl cyanoacetate.It was confirmed that the amidoselenation reaction proceeds with trans stereospecifity.Oxidative elimination of the produced β-amidoalkyl phenyl selenides gives allylic amides selectively in good to excellent yields.These two reactions constitute a good method for conversion of olefins to allylic amides.
