Check Digit Verification of cas no

The CAS Registry Mumber 1192716-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,7,1 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1192716-89:
(9*1)+(8*1)+(7*9)+(6*2)+(5*7)+(4*1)+(3*6)+(2*8)+(1*9)=174
174 % 10 = 4
So 1192716-89-4 is a valid CAS Registry Number.

Microwave-assisted cycloadditions of 2-alkynylbenzonitriles with sodium azide: selective synthesis of tetrazolo[5,1-a]pyridines and 4,5-disubstituted-2H-1,2,3-triazoles

Tsai, Chih-Wei,Yang, Shyh-Chyun,Liu, Ya-Ming,Wu, Ming-Jung

experimental part, p. 8367 - 8372 (2009/12/24)

Under microwave irradiation (75 W), treatment of 2-alkynylbenzonitriles with 1.5 equiv of sodium azide in DMSO at 140 °C gave 4,5-disubstituted-2H-1,2,3-triazoles in 60-99% yields. Additionally, adding 8 equiv of ZnBr2 and using 8 equiv of sodi
