496-83-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 496-83-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 496-83:
(5*4)+(4*9)+(3*6)+(2*8)+(1*3)=93
93 % 10 = 3
So 496-83-3 is a valid CAS Registry Number.

Sensitized Photooxygenation of Silyl Enol Ethers of Cyclic Ketones

Friedrich, Edgar,Lutz, Werner

, p. 1245 - 1263 (2007/10/02)

α,β-Unsaturated and α-hydroxy ketones are accessible in prototropic ene-reactions with singlet oxygen by sensitized photooxygenation of cyclic silyl enol ethers and subsequent reduction and solvolysis.In a competing silatropic ene-reaction α-silyloxyketones are formed.Formation of different products depends on ring size, configuration and substitution.At C-6 chirally substituted 2-cyclohexenones are synthesized for the first time by sensitized photooxygenation of chiral silyl enol ethers of optically active starting ketones.
