Check Digit Verification of cas no

The CAS Registry Mumber 99722-93-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,2 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99722-93:
(7*9)+(6*9)+(5*7)+(4*2)+(3*2)+(2*9)+(1*3)=187
187 % 10 = 7
So 99722-93-7 is a valid CAS Registry Number.

Palladium-Catalyzed, Atmospheric Pressure Ethoxycarbonylation of Allylic Halides under the Influence of Sodium Ethoxide. A Facile Synthesis of β,γ-Unsaturated Esters

Kiji, Jitsuo,Okano, Tamon,Konishi, Hisatoshi,Nishiumi, Wataru

, p. 1873 - 1876 (2007/10/02)

Atmospheric pressure ethoxycarbonylation of allylic halides is realized under the influence of sodium ethoxide.This reaction is catalyzed by Na2PdCl4-bis(diphenylphosphino)ethane (dppe) and offers a convenient synthetic method to β,γ-unsaturated esters.
