1178972-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1178972-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,8,9,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1178972-91:
(9*1)+(8*1)+(7*7)+(6*8)+(5*9)+(4*7)+(3*2)+(2*9)+(1*1)=212
212 % 10 = 2
So 1178972-91-2 is a valid CAS Registry Number.

Alternative approach to 1,2,4-triazole-3-carboxamides
Ellis, David
experimental part, p. 2585 - 2595 (2009/12/26)
The conversion of trichloromethyl and tribromomethyltriazoles to the corresponding carboxamide derivatives is described. The trihalomethyl analogs are straightforward to make and react readily with a range of amines to produce carboxamides. The strategy a
