Check Digit Verification of cas no

The CAS Registry Mumber 1380313-50-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,3,1 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1380313-50:
(9*1)+(8*3)+(7*8)+(6*0)+(5*3)+(4*1)+(3*3)+(2*5)+(1*0)=127
127 % 10 = 7
So 1380313-50-7 is a valid CAS Registry Number.

Stereoselective synthesis of norephedrine and norpseudoephedrine by using asymmetric transfer hydrogenation accompanied by dynamic kinetic resolution

Lee, Hyeon-Kyu,Kang, Soyeong,Choi, Eun Bok

, p. 5454 - 5460 (2012)

Each of the enantiomers of both norephedrine and norpseudoephedrine were stereoselectively prepared from the common, prochiral cyclic sulfamidate imine of racemic 1-hydroxy-1-phenyl-propan-2-one by employing asymmetric transfer hydrogenation (ATH) catalyzed by the well-defined chiral Rh-complexes, (S,S)- or (R,R)-Cp*RhCl(TsDPEN), and HCO2H/Et3N as the hydrogen source. The ATH processes are carried out under mild conditions (rt, 15 min) and are accompanied by dynamic kinetic resolution.
