197392-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197392-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,3,9 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197392-99:
(8*1)+(7*9)+(6*7)+(5*3)+(4*9)+(3*2)+(2*9)+(1*9)=197
197 % 10 = 7
So 197392-99-7 is a valid CAS Registry Number.

Synthesis of linear alkyl-bridged 2,2'-bipyridine/catechol ligands
Albrecht, Markus,Riether, Cyrill
, p. 957 - 962 (2007/10/03)
Linear alkyl-bridged 2,2'-bipyridine/catechol compounds [1,12-14, 19]-H2 and [2,20]-H4 can be easily prepared by the addition of lithiated 5,5'-methyl-2,2'-bipyridine (3) to 3-(ω-haloalkyl)-substituted 1,2-dimethoxybenzenes 4, 9, 11,
