1269206-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1269206-76-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,2,0 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1269206-76:
(9*1)+(8*2)+(7*6)+(6*9)+(5*2)+(4*0)+(3*6)+(2*7)+(1*6)=169
169 % 10 = 9
So 1269206-76-9 is a valid CAS Registry Number.

Copper-catalyzed direct benzylation or allylation of 1,3-azoles with N -tosylhydrazones
Zhao, Xia,Wu, Guojiao,Zhang, Yan,Wang, Jianbo
, p. 3296 - 3299 (2011/04/24)
Cu-Catalyzed cross-coupling of N-tosylhydrazones with 1,3-azoles leads to the direct C-H benzylation or allylation. Cu carbene migratory insertion is proposed to play the key role in this transformation.
