Check Digit Verification of cas no

The CAS Registry Mumber 1227639-08-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,6,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1227639-08:
(9*1)+(8*2)+(7*2)+(6*7)+(5*6)+(4*3)+(3*9)+(2*0)+(1*8)=158
158 % 10 = 8
So 1227639-08-8 is a valid CAS Registry Number.

Asymmetrie retro- and transfer-aldol reactions catalyzed by a simple chiral primary amine

Luo, Sanzhong,Zhou, Pengxin,Li, Jiuyuan,Cheng, Jin-Pei

supporting information; experimental part, p. 4457 - 4461 (2010/07/15)

(Chemical Figure Presented) One stone four birds: A single chiral primary amine was found to catalyze unprecedented asymmetric retro-aldol and transfer-aldol reactions, leading to four different chiral aldol adducts from one common chiral source with up to 99:1 d.r. and 99% ee (see scheme).
