Check Digit Verification of cas no

The CAS Registry Mumber 1448644-09-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,6,4 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1448644-09:
(9*1)+(8*4)+(7*4)+(6*8)+(5*6)+(4*4)+(3*4)+(2*0)+(1*9)=184
184 % 10 = 4
So 1448644-09-4 is a valid CAS Registry Number.

Chiral oxazoline ligands containing a 1,2,4-triazine ring and their application in the Cu-catalyzed asymmetric Henry reaction

Wolińska, Ewa

, p. 7269 - 7278 (2013/08/23)

Eleven members of new ligand class incorporating a chiral oxazoline and a 1,2,4-triazine ring have been synthesized via Pd-catalyzed amination reaction of 3-halo-1,2,4-triazines with 2-(o-aminophenyl)oxazolines. Buchwald-Hartwig amination of 3-halo-1,2,4-triazines was investigated to establish the best conditions for synthesis of the title ligands. Catalytic activity of the new ligands was evaluated in the asymmetric Henry reaction of nitromethane with a variety of aromatic and aliphatic aldehydes. The β-hydroxy nitroalkanes were obtained in high yields (up to 95%), and moderate-to-good enantioselectivity (up to 82% ee).
