Check Digit Verification of cas no

The CAS Registry Mumber 1453188-73-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,1,8 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1453188-73:
(9*1)+(8*4)+(7*5)+(6*3)+(5*1)+(4*8)+(3*8)+(2*7)+(1*3)=172
172 % 10 = 2
So 1453188-73-2 is a valid CAS Registry Number.

Gold-catalyzed cyclization of 3-(2′-azidoaryl)-1-arylpropargyl carbonates or 3-aryl-1-(2′-azidoaryl)propargyl carbonates to produce quinolines

Zhu, Shugao,Wu, Luling,Huang, Xian

, p. 9120 - 9126 (2013/10/08)

A gold-catalyzed cyclization of 3-(2′-azidoaryl)-1-arylpropargyl carbonates to generate substituted quinolines via a sequence of 3,3-rearrangement, 6-endo-trig cyclization and denitrogenation has been developed. Similar products could be obtained from 3-aryl-1-(2′-azidoaryl) propargyl carbonates under different gold catalytic conditions via a sequential 6-endo-dig cyclization, denitrogenation, and 1,2-H shift process.
