5343-99-7 Usage
General Description
1,2-Naphthalic anhydride, also known as alpha-naphthalic anhydride, is a chemical compound with the molecular formula C12H6O3. It is derived from naphthalene and has two carbonyl groups attached to a naphthalene ring. The substance is a solid crystalline powder, white to light beige in appearance. It is commonly used in organic synthesis and for the manufacture of dyestuffs, pharmaceuticals, and resin additives. However, it is considered hazardous and is known to cause eye irritation and harm to the respiratory system, so it must be handled with caution.
Check Digit Verification of cas no
The CAS Registry Mumber 5343-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5343-99:
(6*5)+(5*3)+(4*4)+(3*3)+(2*9)+(1*9)=97
97 % 10 = 7
So 5343-99-7 is a valid CAS Registry Number.

Photocatalytic degradation of polycyclic aromatic hydrocarbons in GaN:ZnO solid solution-assisted process: Direct hole oxidation mechanism
Kou, Jiahui,Li, Zhaosheng,Guo, Yong,Gao, Jun,Yang, Ming,Zou, Zhigang
experimental part, p. 48 - 54 (2010/10/01)
GaN:ZnO exhibits excellent activity for the photodegradation of PAHs, and the activity can be obviously improved by loading Pt. The degradation of PAHs in the system of GaN:ZnO is induced by the formation of holes. The holes generated then interact with PAHs to produce PAHs+, which is active enough to react with O2.
