Check Digit Verification of cas no
The CAS Registry Mumber 944450-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,4,5 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 944450-49:
(8*9)+(7*4)+(6*4)+(5*4)+(4*5)+(3*0)+(2*4)+(1*9)=181
181 % 10 = 1
So 944450-49-1 is a valid CAS Registry Number.

A highly efficient ruthenium-catalyzed asymmetric reductive amination (ARA) of racemic β-keto lactams with molecular hydrogen and ammonium salts is disclosed for the synthesis of enantiomerically pure primary amino lactams through dynamic kinetic resolution (DKR). By this approach, a range of syn primary β-amino lactams were obtained in high yields with high chemo-, enantio-, and diastereoselectivity (up to 98 % yield, 99 % ee, >20:1 d.r., syn products). The utility of the products has been demonstrated by rapid access to a key synthetic intermediate towards biologically active drug molecules. Meanwhile, mechanistic studies and control experiments indicate that the reaction may proceed through the hydrogenation of an iminium intermediate.
