6,7-Cyclopentanochrysene is a polycyclic aromatic hydrocarbon (PAH) with a molecular formula of C21H16. It is formed by the fusion of a cyclopentane ring onto the chrysene molecule, which is itself a PAH consisting of four fused benzene rings. 6,7-cyclopentanochrysene is known for its potential mutagenicity and carcinogenicity, as it can interact with DNA and cause mutations. Due to its structural similarity to other PAHs, 6,7-cyclopentanochrysene is often found in environments where incomplete combustion of organic materials occurs, such as in industrial processes, vehicle emissions, and tobacco smoke. It is also a byproduct of certain chemical reactions and can be present in polluted air, water, and soil. The compound's presence in the environment is a concern due to its toxic properties, and efforts are made to monitor and control its levels to protect public health.

4766-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4766-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4766-40:
(6*4)+(5*7)+(4*6)+(3*6)+(2*4)+(1*0)=109
109 % 10 = 9
So 4766-40-9 is a valid CAS Registry Number.
