Check Digit Verification of cas no

The CAS Registry Mumber 1197874-32-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,8,7 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1197874-32:
(9*1)+(8*1)+(7*9)+(6*7)+(5*8)+(4*7)+(3*4)+(2*3)+(1*2)=210
210 % 10 = 0
So 1197874-32-0 is a valid CAS Registry Number.

Chiral acid-catalyzed asymmetric nazarov reaction: Nucleophilic construction of a quaternary asymmetric center at the a-position of the keto function

Yaji, Kentaro,Shindo, Mitsuru

, p. 2524 - 2528 (2009)

A chiral Lewis acid catalyzed enantioselective Nazarov reaction affording -alkoxy cyclopentenones has been developed. This is the first example for construction of an asymmetric quaternary center by using the monodentate coordinated divinyl ketones via th
