5660-63-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5660-63-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,6 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5660-63:
(6*5)+(5*6)+(4*6)+(3*0)+(2*6)+(1*3)=99
99 % 10 = 9
So 5660-63-9 is a valid CAS Registry Number.

Catalytic migratory oxidative coupling of nitrones

Hashizume, Shogo,Oisaki, Kounosuke,Kanai, Motomu

supporting information; experimental part, 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.
