Check Digit Verification of cas no

The CAS Registry Mumber 1252763-39-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,7,6 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1252763-39:
(9*1)+(8*2)+(7*5)+(6*2)+(5*7)+(4*6)+(3*3)+(2*3)+(1*9)=155
155 % 10 = 5
So 1252763-39-5 is a valid CAS Registry Number.

A thiourea-oxazoline library with axial chirality: Ligand synthesis and studies of the palladium-catalyzed enantioselective bis(methoxycarbonylation) of terminal olefins

supporting information; experimental part, p. 1955 - 1966 (2010/11/03)

We report herein the synthesis of novel chiral S,N-heterobidentate thiourea-oxazoline ligands and their application to palladium-catalyzed enantioselective bis(methoxycarbonylation)s of terminal olefins under mild conditions. Copper salts were found to play multiple roles in this reaction. Substituted 2- phenylsuccinates were obtained in >90% yield and up to 84% ee under optimized conditions.
