Check Digit Verification of cas no

The CAS Registry Mumber 1320257-23-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,0,2,5 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1320257-23:
(9*1)+(8*3)+(7*2)+(6*0)+(5*2)+(4*5)+(3*7)+(2*2)+(1*3)=105
105 % 10 = 5
So 1320257-23-5 is a valid CAS Registry Number.

Rhodium-catalyzed asymmetric arylation of β,γ-unsaturated α-ketoamides for the construction of nonracemic γ,γ- diarylcarbonyl compounds

Wang, Juanjuan,Wang, Min,Cao, Peng,Jiang, Liyin,Chen, Guihua,Liao, Jian

supporting information, p. 6673 - 6677 (2014/07/08)

A highly regio- and enantioselective rhodium-catalyzed 1,4-addition of arylboronic acids to β,γ-unsaturated α-ketoamides using a simple new chiral sulfinylphosphine ligand is described. This transformation provides an attractive approach to construct chiral nonracemic γ,γ-diarylsubstituted carbonyl compounds, as exemplified in the concise syntheses of sertraline and tetrahydroquinoline-2-carboxylamide. Constructing chiral carbonyls: A simple new chiral sulfinylphosphine ligand L was developed, which promoted excellent 1,4-selectivities and enantioselectivities in the rhodium-catalyzed conjugate addition of arylboronic acids to β,γ-unsaturated α-ketoamides. The desired γ,γ-diaryl-α-ketocarbonyl compounds were afforded with high yields and high optical purities.
