107403-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107403-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,4,0 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 107403-28:
(8*1)+(7*0)+(6*7)+(5*4)+(4*0)+(3*3)+(2*2)+(1*8)=91
91 % 10 = 1
So 107403-28-1 is a valid CAS Registry Number.

Palladium Catalysis in the Preparation of Alkynylpyrimidines
Solberg, Jan,Undheim, Kjell
, p. 381 - 386 (2007/10/02)
4-Ethynyl derivatives of 5-chloro-2-methylthiopyrimidines, and of 5-chloro-2(1H)-pyrimidinones as trimethylsilyl derivatives, have been prepared by cross-coupling reactions between 4-iodopyrimidines and acetylenes using palladium catalysis.Reactions for t
