Check Digit Verification of cas no

The CAS Registry Mumber 135507-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135507-99:
(8*1)+(7*3)+(6*5)+(5*5)+(4*0)+(3*7)+(2*9)+(1*9)=132
132 % 10 = 2
So 135507-99-2 is a valid CAS Registry Number.

Manganese(III)-Mediated Free-Radical Cyclization of Active Methylene Compounds, Alkenes and Molecular Oxygen. Syntheses of Sulfur- and Phosphorus-Containing 1,2-Dioxan-3-ols

Qian, Chang-Yi,Nishino, Hiroshi,Kurosawa, Kazu

, p. 209 - 216 (2007/10/02)

The reactions of β-keto sulfoxide, β-keto sulfones, or β-keto phosphinate with 1,1-disubstituted ethenes in the presence of manganese(III) acetate and molecular oxygen yielded 4-phenylsulfinyl-, 4-phenylsulfonyl-, or 4-phosphinoyl-1,2-dioxan-3-ols 3 in moderate-to-good yields. m-Chloroperbenzoic acid oxidation of 4-phenylsulfinyl-1,2-dioxan-3-ols gave the corresponding 4-phenylsulfonyl derivatives.The temperature dependence of the reactions was observed and the stereochemistry of the 1,2-dioxan-3-ols are discused.
