349081-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 349081-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,0,8 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 349081-37:
(8*3)+(7*4)+(6*9)+(5*0)+(4*8)+(3*1)+(2*3)+(1*7)=154
154 % 10 = 4
So 349081-37-4 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.
