1H-Naphtho[3,2,1,8-defg]chrysene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C24H14. It is a structural isomer of chrysene, featuring a naphthalene ring fused to the chrysene core. 1H-Naphtho[3,2,1,8-defg]chrysene(7CI,8CI,9CI) is known for its complex molecular structure, consisting of multiple fused benzene rings. It is not commonly found in nature but can be synthesized in the laboratory. Due to its large molecular size and aromatic nature, 1H-Naphtho[3,2,1,8-defg]chrysene is of interest in chemical research, particularly in the study of PAHs and their potential applications in materials science and organic chemistry. However, like many PAHs, it may also have environmental and health implications due to its potential carcinogenic properties, and thus its handling and use are subject to safety considerations.

190-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 190-99-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 190-99:
(5*1)+(4*9)+(3*0)+(2*9)+(1*9)=68
68 % 10 = 8
So 190-99-8 is a valid CAS Registry Number.
