Check Digit Verification of cas no

The CAS Registry Mumber 199189-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 199189-49:
(8*1)+(7*9)+(6*9)+(5*1)+(4*8)+(3*9)+(2*4)+(1*9)=206
206 % 10 = 6
So 199189-49-6 is a valid CAS Registry Number.

Asymmetric diels-alder reactions of sulfonyl-functionalized α,β-unsaturated ketones with cyclopentadiene catalyzed by chiral lewis acid

Pei, Wen,Wang, Yu-Guang,Wang, Yong-Jiang,Sun, Li

, p. 3383 - 3388 (2008)

Asymmetric Diels-Alder reactions of (E)-1-substituted sulfonyl-3-penten-2- ones with cyclopentadiene catalyzed by a chiral titanium reagent were investigated. The enantioselectivity was studied with different substituents in the position of sulfonyl moiet
