Check Digit Verification of cas no

The CAS Registry Mumber 176-35-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,7 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 176-35:
(5*1)+(4*7)+(3*6)+(2*3)+(1*5)=62
62 % 10 = 2
So 176-35-2 is a valid CAS Registry Number.

SYNTHESIS AND EQUILIBRIUM STUDIES OF NEW DIHYDROTHIOPHENE SULFOXIDES

Miklos, Peter,Senning, Alexander

, p. 249 - 254 (1987)

Oxidation of the Knoevenagel condensation products 2 of 3-oxo-tetrahydrothiophene (1) and active methylene compounds of the type Z-CH2-COOH with an H2O2/V2O5/t-BuOH reagent furnishes the corresponding sulfoxides 3 in excellent yields.The isomer distributions of the sulfides 2 and the sulfoxides 3 reflect peculiarities of hydrothiophenes as compared to similar open-chain systems and establish that the stabilizing effect of the sulfoxide group on β,γ-double bonds is greater than the corresponding effect of so strongly stabilizing groups as CN and COOR.
