Check Digit Verification of cas no

The CAS Registry Mumber 123358-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,5 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123358-81:
(8*1)+(7*2)+(6*3)+(5*3)+(4*5)+(3*8)+(2*8)+(1*1)=116
116 % 10 = 6
So 123358-81-6 is a valid CAS Registry Number.

Temperature, Solvent, and Substituent Effects on the Singlet Oxidations of Allylic Phenyl Sulfoxides, Sulfones, and Sulfides

Clennan, Edward L.,Chen, Xiangning

, p. 8212 - 8218 (2007/10/02)

The reaction of singlet oxygen with a series of allylic sulfoxides, sulfones, and sulfides have been examined as a function of extent of reaction, temperature, and solvent.Hydroperoxy groups but not alkyl, hydrogen, or hydroxyl on chiral carbons β to sulfide sulfur induce diastereoselective sulfoxide formations.Evidence is presented that suggests that the oxidation at sulfur occurs with anchimeric assistance from the hydroperoxy group via a favorable sulfurane-like transition state.
