1263040-34-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263040-34-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,0,4 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1263040-34:
(9*1)+(8*2)+(7*6)+(6*3)+(5*0)+(4*4)+(3*0)+(2*3)+(1*4)=111
111 % 10 = 1
So 1263040-34-1 is a valid CAS Registry Number.

Pd-catalyzed Negishi coupling of pyrazole triflates with alkyl zinc halides
Zhang, Ting,Gao, Xiaodi,Wood, Harold B.
experimental part, p. 311 - 313 (2011/02/26)
A mild, functional group tolerant palladium-catalyzed Negishi coupling of pyrazole triflates and nonaflates with alkyl, benzyl, and aryl zinc halides has been developed. It allows quick access to 3-substituted pyrazole analogs at late stage via common syn
