Check Digit Verification of cas no
The CAS Registry Mumber 81620-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81620-99:
(7*8)+(6*1)+(5*6)+(4*2)+(3*0)+(2*9)+(1*9)=127
127 % 10 = 7
So 81620-99-7 is a valid CAS Registry Number.

Isoxazoles VI: Aspects of the chemical stability of a new naphthoquinone-amine in acidic aqueous solution
Longhi,De Bertorello
, p. 754 - 757 (2007/10/02)
Some aspects of the chemical degradation of N-(3,4-dimethyl-5-isoxazolyl)-4-amino-1,2-naphthoquinone were investigated as a function of pH and temperature. In acid and neutral pH, four main degradation products were identified: 2-hydroxy-1,4-naphthoquinone, 2-butanone, ammonia, and hydroxylamine. No significant buffer effects were observed for the buffer species used in this study. The pH-rate profile exhibited a specific acid catalysis which is important at pH values 3.5, and an inflection point at pH 1.10 corresponding to a pK(a) value. From Arrhenius plots, the activation energy was found to be 17.8 ± 0.3 kcal/mol.
