Check Digit Verification of cas no

The CAS Registry Mumber 214334-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,3,3 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 214334-32:
(8*2)+(7*1)+(6*4)+(5*3)+(4*3)+(3*4)+(2*3)+(1*2)=94
94 % 10 = 4
So 214334-32-4 is a valid CAS Registry Number.

Lewis Acid-Promoted Disproportionation Reaction of Aromatic Vinyl Ethers and Acetals and Its Application to the Synthesis of Paracotoin

Gong, Young Dae,Tanaka, Hiroko,Iwasawa, Nobuharu,Narasaka, Koichi

, p. 2181 - 2185 (2007/10/03)

Aromatic vinyl ethers and acetals underwent a novel addition-fragmentation reaction affording olefins and esters in the presence of a Lewis acid. This reaction was applied to intramolecular cyclization reaction, giving five or six membered ring compounds in good yields. Paracotoin, an intermediate in the biosynthesis of shikimic acid, was synthesized using this cyclization reaction as the key step.
