263399-28-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263399-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,3,9 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 263399-28:
(8*2)+(7*6)+(6*3)+(5*3)+(4*9)+(3*9)+(2*2)+(1*8)=166
166 % 10 = 6
So 263399-28-6 is a valid CAS Registry Number.

The photochemistry of an aryl pentazole in liquid solutions: The anionic 4-oxidophenylpentazole (OPP)
Geiger, Uzi,Haas, Yehuda,Grinstein, Dan
, p. 53 - 61 (2014)
This paper reports a study on the photolysis of an aryl pentazole in solution. 4-Oxidophenylpentazole (OPP) was irradiated in water and in acetonitrile at its first absorption band (320 and 370 nm, respectively) and at 193 nm. 4-Oxidophenylazide (OPA) was
