Check Digit Verification of cas no

The CAS Registry Mumber 1187944-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,9,4 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1187944-13:
(9*1)+(8*1)+(7*8)+(6*7)+(5*9)+(4*4)+(3*4)+(2*1)+(1*3)=193
193 % 10 = 3
So 1187944-13-3 is a valid CAS Registry Number.

A click chemistry approach for the synthesis of macrocycles from aryl amide-based precursors directed by hydrogen bonding

Zhu, Yuan-Yuan,Wang, Gui-Tao,Li, Zhan-Ting

experimental part, p. 3243 - 3250 (2009/10/24)

This paper describes the synthesis of four aryl amide-based macrocycles through the 1 + 1 formation of two 1,2,3-triazole units by click chemistry. Two series of aryl amide-based precursors that bear two azide or acetylene units have been prepared. Intram
