Check Digit Verification of cas no
The CAS Registry Mumber 56434-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,3 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56434-29:
(7*5)+(6*6)+(5*4)+(4*3)+(3*4)+(2*2)+(1*9)=128
128 % 10 = 8
So 56434-29-8 is a valid CAS Registry Number.

Preparation of Azolopyridazinecarboxylic Acids

Oxidation reactions of various methyl substituted azolopyridazines 2a-d, 3a-h, 4a,b were investigated in order to gain access to the title compounds.This procedure was found to be of limited scope affording only the carboxylic acids 5, 7 and 9.A variety of novel azolopyridazinecarboxylic acid methyl esters bearing one or two methoxycarbonyl groups at the pyridazine core 17,18 and 12,14,16,20, respectively, however, could be prepared by means of a regioselective radical substitution process.
