Check Digit Verification of cas no

The CAS Registry Mumber 1401675-18-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,6,7 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1401675-18:
(9*1)+(8*4)+(7*0)+(6*1)+(5*6)+(4*7)+(3*5)+(2*1)+(1*8)=130
130 % 10 = 0
So 1401675-18-0 is a valid CAS Registry Number.

One-pot synthesis of 4(3H)-quinazolinones from azides, alkynes, anilines, and carbon monoxide

Shen, Yang,Han, Chao,Cai, Shuying,Lu, Ping,Wang, Yanguang

supporting information, p. 5671 - 5673 (2012/10/29)

A one-pot synthesis of 4(3H)-quinazolinones from terminal alkynes, sulphonyl azide, o-iodoanilines, and carbon monoxide has been developed. This cascade process includes the copper-catalyzed three-component reaction of alkyne, azide and amine, the palladium-catalyzed carbonylation, and the Lewis acid catalyzed hydrolysis of sulfonamide.
