Check Digit Verification of cas no

The CAS Registry Mumber 77796-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,9 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77796-18:
(7*7)+(6*7)+(5*7)+(4*9)+(3*6)+(2*1)+(1*8)=190
190 % 10 = 0
So 77796-18-0 is a valid CAS Registry Number.

Reaction Mechanism of Cathodic Crossed Coupling of Acetone with Unsaturated Compounds in Acidic Solution

Koizumi, Toshio,Fuchigami, Toshio,Kandeel, Zaghloul El-Shahat,Sato, Norio,Nonaka, Tsutomu

, p. 757 - 762 (2007/10/02)

It was confirmed that the cathodic crossed coupling of acetone with unsaturated compounds in aqueous sulfuric acid could proceed smoothly, when the compounds which had radical-acceptable double bonds and were adsorbed on a mercury cathode were used.From this fact, it was concluded that the coupling occurs via the addition of a radical intermediate formed by the one-electron reduction of acetone to the double bonds on the cathode surface.Possibility of the addition of an anionic intermediate derived from acetone was excluded by no occurrence of the coupling of acetone with a polar acetylenic triple bond compound adsorbed on the cathode.
