Check Digit Verification of cas no

The CAS Registry Mumber 67738-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,3 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67738-33:
(7*6)+(6*7)+(5*7)+(4*3)+(3*8)+(2*3)+(1*3)=164
164 % 10 = 4
So 67738-33-4 is a valid CAS Registry Number.

Chemistry of Singlet Oxygen. 52. Reaction with trans-Stilbene

Kwon, Byoung-Mog,Foote, Christopher S.,Khan, Saeed I.

, p. 3378 - 3382 (1989)

Substituted trans-stilbenes react with singlet oxygen to give substituted diendoperoxides along with corresponding epoxides, cis-stilbenes, and benzaldehydes.The diendoperoxides rearrange readily to keto compounds on treatment with base.In methyl alcohol, solvent adducts are isolated.Monoendoperoxides are the primary products isolated from the photooxygenation of mono- and dimethoxystilbenes.Structures of several products were confirmed by NMR and X-ray crystallography.The results suggest that endoperoxide formation occurs via a polar intermediate such as a perepoxide or zwitterion.
