Check Digit Verification of cas no

The CAS Registry Mumber 1273584-09-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,8 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1273584-09:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*8)+(3*4)+(2*0)+(1*9)=170
170 % 10 = 0
So 1273584-09-0 is a valid CAS Registry Number.

N-(heteroarenesulfonyl)prolinamides-catalyzed aldol reaction between acetone and aryl trihalomethyl ketones

Hara, Noriyuki,Tamura, Ryota,Funahashi, Yasuhiro,Nakamura, Shuichi

supporting information; experimental part, p. 1662 - 1665 (2011/05/11)

Enantiomerically enriched trihalomethyl-substituted alcohols having a quaternary chiral carbon center can be prepared by the catalytic enantioselective cross-aldol reaction of acetone with trihalomethyl ketones by using N-(8-quinolinesulfonyl)prolinamide as an organocatalyst. The MO calculations elucidate that the hydrogen bonding between the sulfonimide proton and the 8-quinolyl nitrogen atom plays an important role in exerting the enantioselectivity of the reaction.
