225932-11-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 225932-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,9,3 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 225932-11:
(8*2)+(7*2)+(6*5)+(5*9)+(4*3)+(3*2)+(2*1)+(1*1)=126
126 % 10 = 6
So 225932-11-6 is a valid CAS Registry Number.

Synthesis of 5,5'-disubstituted 2,2'-bipyridines for modular chemistry
Henze, Oliver,Lehmann, Uwe,Schlüter, A. Dieter
, p. 683 - 687 (2007/10/03)
A 0.5-11 g scale synthesis of the 5,5'-disubstituted 2,2'-bipyridines 8 is described. The pyridine units are connected to one another by Pd-catalyzed cross-coupling reactions. This method allows one to introduce bromo functions and flexible chains at the
