Check Digit Verification of cas no

The CAS Registry Mumber 175286-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 175286-57:
(8*1)+(7*7)+(6*5)+(5*2)+(4*8)+(3*6)+(2*5)+(1*7)=164
164 % 10 = 4
So 175286-57-4 is a valid CAS Registry Number.

Structure and asymmetric diels-alder reactions of optically active allene-1,3-dicarboxylates

Ikeda, Izumi,Honda, Kazuhiko,Osawa, Eiji,Shiro, Motoo,Aso, Mariko,Kanematsu, Ken

, p. 2031 - 2037 (2007/10/03)

Optically active allene-1,3-dicarboxylates (1a and 2a), which contain the axial asymmetry of the allene moiety, were prepared. The Diels-Alder reaction of 1a and 2a with cyclopentadiene afforded the 1:1 (1a or 2a to cyclopentadiene) endo adducts 3a and 4a through the combination of the sterically favorable approach of the diene and the dienophile owing to the axial asymmetry of the allene moiety and the effective secondary orbital interaction. The absolute configurations of 3a and 4a were determined by chemical transformation and X-ray analysis. The absolute configuration of the axial asymmetry of 1a was also determined to be R by X-ray analysis.
