Check Digit Verification of cas no

The CAS Registry Mumber 89972-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,7 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89972-26:
(7*8)+(6*9)+(5*9)+(4*7)+(3*2)+(2*2)+(1*6)=199
199 % 10 = 9
So 89972-26-9 is a valid CAS Registry Number.

SYNTHESIS AND BASE-CATALYZED RECYCLIZATION OF 3-ARYLAMINOCARBONYLANTHRA-6-ISOXAZOLONES

Gornostaev, L. M.,Lavrikova, T. I

, p. 1279 - 1282 (2007/10/02)

Thermolysis of 1-azido-2-arylaminocarbonylanthraquinones in nonpolar solvents leads to 3-arylaminocarbonylanthra-6-isoxazolones.By the action of bases, these compounds recyclize in aprotic solvents into 2-arylanthra-1H-pyrazolin-3,6,11-trio
