Check Digit Verification of cas no

The CAS Registry Mumber 1316673-54-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,6,6,7 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1316673-54:
(9*1)+(8*3)+(7*1)+(6*6)+(5*6)+(4*7)+(3*3)+(2*5)+(1*4)=157
157 % 10 = 7
So 1316673-54-7 is a valid CAS Registry Number.

Catalytic migratory oxidative coupling of nitrones

Hashizume, Shogo,Oisaki, Kounosuke,Kanai, Motomu

, p. 4288 - 4291 (2011/10/09)

A Cu(I)-catalyzed migratory oxidative coupling between nitrones and heterocycles or a methylamine is described. Selective C-C bond-formation proceeds through cleavage of two C(sp3)-H bonds concomitant with C=N double bond-migration. The reaction provides an alternating nitrone moiety, allowing for further synthetically useful transformations. Radical clock studies suggest that the nucleophilic addition of nitrones to an oxidatively generated carbocation is a key step.
