1142400-17-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1142400-17-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,4,0 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1142400-17:
(9*1)+(8*1)+(7*4)+(6*2)+(5*4)+(4*0)+(3*0)+(2*1)+(1*7)=86
86 % 10 = 6
So 1142400-17-6 is a valid CAS Registry Number.

Rapid, microwave-assisted synthesis of N1-substituted 3-amino-1,2,4-triazoles
Meng, Jerry,Kung, Pei-Pei
experimental part, p. 1667 - 1670 (2009/09/05)
A robust, regioselective synthesis of 3-amino-1,2,4-triazoles is described. This reaction employs a key intermediate 2, which is coupled to carboxylic acids in good yields to afford intermediates 3a-d. These entities, in turn, react with a variety of hydr
