Check Digit Verification of cas no

The CAS Registry Mumber 1439401-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,4,0 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1439401-68:
(9*1)+(8*4)+(7*3)+(6*9)+(5*4)+(4*0)+(3*1)+(2*6)+(1*8)=159
159 % 10 = 9
So 1439401-68-9 is a valid CAS Registry Number.

Metal-Free Synthesis of 3-Arylquinolin-2-ones from Acrylic Amides via a Highly Regioselective 1,2-Aryl Migration: An Experimental and Computational Study

Liu, Le,Zhang, Tonghuan,Yang, Yun-Fang,Zhang-Negrerie, Daisy,Zhang, Xinhao,Du, Yunfei,Wu, Yun-Dong,Zhao, Kang

, p. 4058 - 4065 (2016/06/08)

Combined experimental and theoretical investigations into the phenyliodine bis(trifluoroacetate) (PIFA)-mediated reaction of N-arylcinnamamide to produce 3-arylquinolin-2-one derivatives have been conducted. High regioselectivity during the aryl migration process was observed in 3,3-disubstituted acrylamides. Density functional theory calculation was conducted in an attempt to understand the mechanism and the origin of the regioselectivity. On the basis of both the experimental and the theoretical results, a mechanism involving an oxidative annulation, followed by an aryl migration, has been proposed. The annulation is the regioselectivity determining step.
