Check Digit Verification of cas no

The CAS Registry Mumber 27749-03-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 27749-03:
(7*2)+(6*7)+(5*7)+(4*4)+(3*9)+(2*0)+(1*3)=137
137 % 10 = 7
So 27749-03-7 is a valid CAS Registry Number.

Copper-catalyzed C-N coupling reaction of tosylhydrazones

Wu, Xufeng,Li, Lingyu,Jiang, Wenlong,Zhou, Lihong,Zeng, Qingle

, (2018)

Tosylhydrazones are a kind of labile and highly reactive compounds, which are apt to be transformed into reactive diazo compounds and then into extremely reactive carbenes under the basic condition. In order to fulfil the valuable C-N coupling reaction, diaryliodonium salts are evaluated and prove to be a class of efficient electrophiles. The reaction with ligand-free copper salt as catalyst shows a wide range of substrate scope. A plausible mechanism is proposed.
