Check Digit Verification of cas no

The CAS Registry Mumber 1273593-11-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,9 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1273593-11:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*9)+(3*3)+(2*1)+(1*1)=165
165 % 10 = 5
So 1273593-11-5 is a valid CAS Registry Number.

Highly enantioselective Michael addition of cyclopentanone with chalcones via novel di-iminium mechanism

Wang, Junfeng,Wang, Xin,Ge, Zemei,Cheng, Tieming,Li, Runtao

supporting information; experimental part, p. 1751 - 1753 (2010/07/06)

The highly efficient asymmetric Michael addition reactions of cyclopentanone with chalcones were catalyzed by a simple and commercially available chiral 1,2-diaminocyclohexane-hexanedioic acid, and exhibited good yields (up to 92%) and excellent enantioselectivities (up to 99% ee). A new di-iminium mechanism for the reaction was proposed.
