Check Digit Verification of cas no

The CAS Registry Mumber 1428865-38-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,8,6 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1428865-38:
(9*1)+(8*4)+(7*2)+(6*8)+(5*8)+(4*6)+(3*5)+(2*3)+(1*8)=196
196 % 10 = 6
So 1428865-38-6 is a valid CAS Registry Number.

PhI(OAc)2-mediated intramolecular oxidative aryl-aldehyde C sp 2-C sp 2 bond formation: Metal-free synthesis of acridone derivatives

Zheng, Zisheng,Dian, Longyang,Yuan, Yucheng,Zhang-Negrerie, Daisy,Du, Yunfei,Zhao, Kang

, p. 7451 - 7458 (2014/09/17)

A metal-free protocol for direct aryl-aldehyde Csp2-Csp 2 bond formation via a PhI(OAc)2-mediated intramolecular cross-dehydrogenative coupling (CDC) of various 2-(N-arylamino)aldehydes was developed. The novel methodology requires no need of preactivation of the aldehyde group, is applicable to a large variety of functionalized substrates, and most of all provides a convenient approach to the construction of biologically important acridone derivatives.
