Check Digit Verification of cas no

The CAS Registry Mumber 1092940-31-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,9,4 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1092940-31:
(9*1)+(8*0)+(7*9)+(6*2)+(5*9)+(4*4)+(3*0)+(2*3)+(1*1)=152
152 % 10 = 2
So 1092940-31-2 is a valid CAS Registry Number.

Synthesis of chiral N-heterocyclic carbene ligands with rigid backbones and application to the palladium-catalyzed enantioselective intramolecular α-arylation of amides

Liu, Lantao,Ishida, Naoki,Ashida, Shinji,Murakami, Masahiro

, p. 1666 - 1669 (2011/05/11)

Chiral N-heterocyclic carbene (NHC) ligands having a 2,2′- bisquinoline-based C2 symmetric skeleton were developed. The ligands exhibited good enantioselectivity in palladium-catalyzed intramolecular α-arylation of amides to give 3,3-disubsituted oxindoles.

Bulky chiral carbene ligands and their application in the palladium- catalyzed asymmetric intramolecular α-arylation of amides

Kuendig, E. Peter,Seidel, Thomas M.,Jia, Yi-Xia,Bernardinelli, Gerald

, p. 8484 - 8487 (2008/09/18)

(Chemical Equation Presented) Bring on the big cats: New, C 2-symmetric bulky N-heterocyclic carbene ligands bring major improvements in the palladium-catalyzed asymmetric intramolecular α-arylation of amides to give oxindoles (see picture, dba=trans,trans- dibenzylideneacetone), which are formed in high yield and excellent enantiomeric purity.
