Check Digit Verification of cas no

The CAS Registry Mumber 1569299-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,2,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1569299-55:
(9*1)+(8*5)+(7*6)+(6*9)+(5*2)+(4*9)+(3*9)+(2*5)+(1*5)=233
233 % 10 = 3
So 1569299-55-3 is a valid CAS Registry Number.

Convergent catalysis: Asymmetric synthesis of dihydroquinolines using a combined metal catalysis and organocatalysis approach

Rueping, Magnus,Dufour, Jeremy,Bui, Lan

, p. 1021 - 1025 (2014/04/03)

A convergent catalysis approach has been developed. The combined metal-catalyzed and organocatalyzed cascade consists of two oxidations, an aza-Michael addition and an aldol condensation, and involves a multicatalysis approach to provide 1,2-dihydroquinolines in a highly enantioselective fashion.
