Check Digit Verification of cas no

The CAS Registry Mumber 1308401-00-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,8,4,0 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1308401-00:
(9*1)+(8*3)+(7*0)+(6*8)+(5*4)+(4*0)+(3*1)+(2*0)+(1*0)=104
104 % 10 = 4
So 1308401-00-4 is a valid CAS Registry Number.

Palladium-catalyzed enantioselective intramolecular hydroarylation of alkynes to form axially chiral 4-aryl 2-quinolinones

Shibuya, Tetsuro,Shibata, Yu,Noguchi, Keiichi,Tanaka, Ken

, p. 3963 - 3967 (2011/06/24)

A long-awaited asymmetric version of the intramolecular hydroarylation of alkynes to form fused ring systems has been developed. A cationic palladium(II)/(S)-xyl-H8-binap complex was used to catalyze an enantioselective hydroarylation of alkynes at room temperature to furnish axially chiral 4-aryl 2-quinolinone derivatives in good yields with good enantioselectivity (see scheme; Bn=benzyl).
