Check Digit Verification of cas no
The CAS Registry Mumber 143668-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,6 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143668-57:
(8*1)+(7*4)+(6*3)+(5*6)+(4*6)+(3*8)+(2*5)+(1*7)=149
149 % 10 = 9
So 143668-57-9 is a valid CAS Registry Number.

A modular approach for ligand design for asymmetric allylic alkylations via enantioselective palladium-catalyzed ionizations
Trost, Barry M.,Van Vranken, David L.,Bingel, Carsten
, p. 9327 - 9343 (2007/10/02)
A new class of ligands for asymmetric transition metal catalysis based on 2-(diphenylphosphino)benzoic acid was used in a mechanistically-defined palladium-catalyzed reaction in which enantiodifferentiation was the result of selective ionization of substr
