Check Digit Verification of cas no

The CAS Registry Mumber 1608116-74-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,8,1,1 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1608116-74:
(9*1)+(8*6)+(7*0)+(6*8)+(5*1)+(4*1)+(3*6)+(2*7)+(1*4)=150
150 % 10 = 0
So 1608116-74-0 is a valid CAS Registry Number.

Highly enantioselective Michael addition of diethyl malonate to chalcones catalyzed by cinchona alkaloids-derivatived bifunctional tertiary amine-thioureas bearing multiple hydrogen-bonding donors

Liu, Yulong,Wang, Xie,Wang, Xiaoyun,He, Wei

supporting information, p. 3163 - 3166 (2014/05/06)

Chalcones are still challenge substrates in Michael reactions, and only limited success has been achieved. This work describes a highly enantioselective Michael addition of diethyl malonate with chalcones catalyzed by cinchona alkaloids-derivatived bifunctional tertiary amine-thioureas bearing multiple hydrogen-bonding donors.
