Check Digit Verification of cas no

The CAS Registry Mumber 107202-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,2,0 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107202-32:
(8*1)+(7*0)+(6*7)+(5*2)+(4*0)+(3*2)+(2*3)+(1*2)=74
74 % 10 = 4
So 107202-32-4 is a valid CAS Registry Number.

Catalytic Hydrogenation of Chiral α-Amino and α-Hydroxy Esters at Room Temperature with Nishimura Catalyst without Racemization

Studer, Martin,Burkhardt, Stefan,Blaser, Hans-Ulrich

, p. 802 - 808 (2007/10/03)

The hydrogenation of carboxylic acid derivatives at room temperature was investigated. With a mixed Rh/Pt oxide (Nishimura catalyst), low to medium activity was observed for various α-amino and α-hydroxy esters. At 100 bar hydrogen pressure and 10% catalysts loading, high yields of the desired amino alcohols and diols were obtained without racemization. The most suitable α-substituents were NH2, NHR, and OH, whereas β-NH2 were less effective. Usually, aromatic rings were also hydrogenated, but with the free bases of amino acids as substrates, some selectivity was observed. No reaction was found for α-NR2, α-OR, and unfunctionalized esters; acids and amides were also not reduced under these conditions. A working hypothesis for the mode of action of the catalyst is presented.
