Check Digit Verification of cas no

The CAS Registry Mumber 43227-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,2,2 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 43227-83:
(7*4)+(6*3)+(5*2)+(4*2)+(3*7)+(2*8)+(1*3)=104
104 % 10 = 4
So 43227-83-4 is a valid CAS Registry Number.

Chemistry of Singlet Oxygen. 53. Environmental Effects on the Photooxygenation of 2-Methoxy-3-methyl-2-cyclopenten-1-one

Kwon, Byoung-Mog,Foote, Christopher S.

, p. 3878 - 3882 (2007/10/02)

Photooxygenation of 2-methoxy-3-methyl-2-cyclopenten-1-one (1) gives both ene and dioxetane products.The product distribution depends on temperature and solvent.In CD3OD, the photooxygenation of 1 gives solvent adducts as initial products, and the ratio of stereoisomers is very sensitive to the amount of CD3OD in the reaction mixture.The results are discussed in terms of possible intermediates for the ene and dioxetane products, especially an exciplex.
