Check Digit Verification of cas no

The CAS Registry Mumber 1018901-77-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,8,9,0 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1018901-77:
(9*1)+(8*0)+(7*1)+(6*8)+(5*9)+(4*0)+(3*1)+(2*7)+(1*7)=133
133 % 10 = 3
So 1018901-77-3 is a valid CAS Registry Number.

Highly efficient amine organocatalysts based on bispidine for the asymmetric Michael addition of ketones to nitroolefins

Yang, Zhigang,Liu, Jie,Liu, Xiaohua,Wang, Zhen,Feng, Xiaoming,Su, Zhishan,Hua, Changwei

supporting information; experimental part, p. 2001 - 2006 (2009/08/14)

A highly diastereoselective and enantioselective Michael addition of cyclohexanone, acetone and other ketones to nitroolefins was developed by the use of an amine organocatalyst based on bispidine. Additionally, a theoretical study of transition structures revealed that this bispidinebased primary-secondary amine catalyst could serve through an enamine intermediate and H-bond interaction, which was important for the reactivity and selectivity of this reaction.
