Check Digit Verification of cas no

The CAS Registry Mumber 1227148-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,1,4 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1227148-19:
(9*1)+(8*2)+(7*2)+(6*7)+(5*1)+(4*4)+(3*8)+(2*1)+(1*9)=137
137 % 10 = 7
So 1227148-19-7 is a valid CAS Registry Number.

Noyort's Ts-DPEN ligand: Simple yet effective catalyst for the highly enantioselective michael addition of acetone to nitroalkenes

Peng, Lin,Xu, Xiao-Ying,Wang, Liang-Liang,Huang, Jun,Bai, Jian-Fei,Huang, Qing-Chun,Wang, Li-Xin

, p. 1849 - 1853 (2010)

Highly enantioselective Michael addition of acetone to a variety of nitroalkenes promoted by simple chiral primary amine bifunctional catalysts (e.g., Noyori's Ts-DPEN ligand) together with terephthalic acid in excellent yields (84-99%) and enantioselectivities (93-98 % ee) is reported.
