89174-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89174-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,7 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89174-90:
(7*8)+(6*9)+(5*1)+(4*7)+(3*4)+(2*9)+(1*0)=173
173 % 10 = 3
So 89174-90-3 is a valid CAS Registry Number.

TRANSFORMATIONS OF 1-AZIDO-2-ANTHRAQUINONECARBOXYLIC ACID AND ITS ESTERS
Gornostaev, L. M.,Lavrikova, T. I.
, p. 2012 - 2015 (2007/10/02)
When heated in nonpolar solvents, 1-azido-2-alkoxycarbonylanthraquinones are converted into 3-alkoxycarbonylanthra-6-isoxazolones.The product from the thermolysis of 1-azido-2-anthraquinonecarboxylic acid is 1,3-dihydroanthraisoxazole-3,6,11-trione.
