Check Digit Verification of cas no

The CAS Registry Mumber 70264-96-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,6 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70264-96:
(7*7)+(6*0)+(5*2)+(4*6)+(3*4)+(2*9)+(1*6)=119
119 % 10 = 9
So 70264-96-9 is a valid CAS Registry Number.

Photochemistry of Aliphatic Imides. Synthesis of Azetidine-2,4-diones via Photochemical Isomerization of Succinimides and N-Formyl-N-methyl α, β -Unsaturated Amides

Maruyama, Kazuhiro,Ishitoku, Takeshi,Kubo, Yasuo

, p. 27 - 34 (2007/10/02)

Photochemical reactions of alkyl-substituted succinimides and N-formyl-N-methyl α, β -unsaturated amides were studied.Photolysis of succinimide 1 gave azetidine-2,4-dione 2 together with a small amount of 3.The photoinduced ring-contraction reaction is explained in terms of a two-photon mechanism.Similarly, several other succinimide derivates photochemically gave the corresponding azetidine-2,4-diones.In addition, the photochemical cyclization of 3 to 2 was extended to the synthesis of azetidine-2,4-diones from N-formyl-N-methyl α, β -unsaturated amides.
