Safety Considerations:
Check Digit Verification of cas no
The CAS Registry Mumber 117196-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,9 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117196-08:
(8*1)+(7*1)+(6*7)+(5*1)+(4*9)+(3*6)+(2*0)+(1*8)=124
124 % 10 = 4
So 117196-08-4 is a valid CAS Registry Number.

We report an efficient method for preparing 2,4-dibromopyridine and 4,4'-dibromo-2,2'-bipyridine from the corresponding nitroazine N-oxide in one step via a tandem nucleophilic substitution-N-oxide reduction process. The one step preparation of 4,4'-dihalo-2,2'-bipyridines from dihalopyridines via a Stille reaction is also described. 4,4'-Dibromo-2,2'-bipyridine undergoes selective mono- or disubstitution processes under palladium catalysis. This short synthetic procedure is an efficient and reliable process for preparing conjugated pyridine and 2,2'-bipyridine building blocks for applications in coordination chemistry and materials science.
