Check Digit Verification of cas no

The CAS Registry Mumber 1321077-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,0,7 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1321077-16:
(9*1)+(8*3)+(7*2)+(6*1)+(5*0)+(4*7)+(3*7)+(2*1)+(1*6)=110
110 % 10 = 0
So 1321077-16-0 is a valid CAS Registry Number.

Synthesis of pyrazoles from 2-azidoacrylates and hydrazonyl chlorides

Li, Yao,Hong, Deng,Lu, Ping,Wang, Yanguang

supporting information; experimental part, p. 4161 - 4163 (2011/09/19)

A regioselective synthesis of 1,3,4,5-tetrasubstituted pyrazoles is established between 2-azidoacrylates and hydrazonyl chlorides in the presence of triethylamine. The yields are moderate (43-73%) and a possible mechanism for this transformation is postul
