136220-97-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136220-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,2,2 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136220-97:
(8*1)+(7*3)+(6*6)+(5*2)+(4*2)+(3*0)+(2*9)+(1*7)=108
108 % 10 = 8
So 136220-97-8 is a valid CAS Registry Number.

An efficient synthesis of chiral homophenylalanine derivatives via enantioselective hydrogenation

Li, Xingshu,Yeung, Chi-Hung,Chan, Albert S. C.,Lee, Dong-Sheng,Yang, Teng-Kuei

, p. 3863 - 3867 (2007/10/03)

Chiral homophenylalanine derivatives were synthesized via enantioselective hydrogenation of 5a and 5b catalyzed by rhodium complexes bearing chiral phosphine and phosphinite legands. Enantiomeric excesses up to 96.2% were achieved when S-spiroOP(S-1) was used as a chiral ligand under 500 psi of H2 pressure in acetone.
