213386-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213386-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,3,8 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 213386-56:
(8*2)+(7*1)+(6*3)+(5*3)+(4*8)+(3*6)+(2*5)+(1*6)=122
122 % 10 = 2
So 213386-56-2 is a valid CAS Registry Number.

Synthesis of 1-benzylcinnoline-3-carboxylic acids
Stanczak, Andrzej
, p. 71 - 76 (2007/10/03)
The method or preparation of 1-benzyl substituted 4-imino- and 4-oxocinnoline-3-carboxylic acids is described. These acids were prepared by alkylation with benzyl bromide of the corresponding ethylcinnoline-3-carboxylates. The esters were hydrolyzed to the desired 1-benzylcinnoline-3-carboxylic acids.
