Check Digit Verification of cas no

The CAS Registry Mumber 136744-84-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,4 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136744-84:
(8*1)+(7*3)+(6*6)+(5*7)+(4*4)+(3*4)+(2*8)+(1*4)=148
148 % 10 = 8
So 136744-84-8 is a valid CAS Registry Number.

Enantioselective synthesis of β-amino acids based on BINAP-ruthenium(II) catalyzed hydrogenation

Lubell,Kitamura,Noyori

, p. 543 - 554 (2007/10/02)

BINAP-Ru(II) catalyzed hydrogenation of β-substituted (E)-β-(acylamino)acrylic acids allows efficient enantioselective synthesis of β-amino acids. The Z double bond isomers which possess an intramolecular hydrogen bond between amide and ester groups are more reactive but are hydrogenated with poor enantioselectivity. BINAP-Rh(I) complexes afford only moderate stereoselectivity with the opposite sense of enantioselection.
