Check Digit Verification of cas no

The CAS Registry Mumber 1169874-48-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,7 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1169874-48:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*7)+(3*4)+(2*4)+(1*8)=209
209 % 10 = 9
So 1169874-48-9 is a valid CAS Registry Number.

Synthesis of polysubstituted 1,2-dihydroisoquinolines via a CuI-catalyzed arylation/condensation cascade process

Wu, Yangyang,Zhang, Yihua,Jiang, Yongwen,Ma, Dawei

, p. 3683 - 3685 (2009)

CuI-catalyzed reaction of 1-(2-bromophenyl)-propargylamines 4 with β-keto esters in i-PrOH/H2O (3:1) at 50 °C provides polysubstituted 1,2-dihydroisoquinolines. The transformation involves a cascade intermolecular C-C bond formation and intramo
