1276033-54-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1276033-54-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,0,3 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1276033-54:
(9*1)+(8*2)+(7*7)+(6*6)+(5*0)+(4*3)+(3*3)+(2*5)+(1*4)=145
145 % 10 = 5
So 1276033-54-5 is a valid CAS Registry Number.

Base-mediated intermolecular sp2 C-H bond arylation via benzyne intermediates
Truong, Thanh,Daugulis, Olafs
, p. 4243 - 4245 (2011)
A transition-metal-free method for arylation of heterocycle and arene carbon-hydrogen bonds by aryl chlorides and fluorides has been developed. The reactions proceed via aryne intermediates and are highly regioselective with respect to the C-H bond coupling component.
