Check Digit Verification of cas no

The CAS Registry Mumber 56969-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,6 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 56969-73:
(7*5)+(6*6)+(5*9)+(4*6)+(3*9)+(2*7)+(1*3)=184
184 % 10 = 4
So 56969-73-4 is a valid CAS Registry Number.

Chemoselective Synthesis of N -Arylenaminones and 3-Aroylquinolines by Synergistic Control of Temperature and Amount of Catalyst

Zhou, Pan,Hu, Biao,Rao, Kairui,Li, Lingdan,Yang, Jiao,Gao, Chuanzhu,Wang, Fengping,Yu, Fuchao

supporting information, p. 519 - 524 (2017/11/29)

An efficient and practical method has been developed for the divergent synthesis of N -arylenaminones and 3-aroylquinolines from 2-aminoaryl ketones and N, N -dimethylenaminones in the presence of 4-toluenesulfonic acid through synergistic control of the

ZnCl2-promoted Friedl?nder-type synthesis of 4-substituted 3-aroyl quinolines from o-aminoaryl ketones and enaminones

Luo, Laichun,Zhou, Zongbao,Zhu, Jiayi,Lu, Xue,Wang, Hong

supporting information, p. 4987 - 4990 (2016/10/21)

A practical synthesis of 4-substituted 3-aroyl quinolines via Friedl?nder-type reaction from readily available o-aminoaryl ketones and enaminones was developed. In the presence of ZnCl2, the reaction proceeded smoothly affording the desired products with various functional groups in moderate to good yields.
