Indeno[2,1-b]chromene is a polycyclic aromatic hydrocarbon (PAH) consisting of a fused ring system with a molecular formula of C13H8. It is a colorless crystalline solid with a melting point of 95-97°C. indeno[2,1-b]chromene is formed during the incomplete combustion of organic materials, such as coal, oil, and tobacco, and is considered a potential environmental pollutant due to its toxic and carcinogenic properties. The structure of indeno[2,1-b]chromene features a central indene core with a chromene ring attached to it, which contributes to its unique chemical and physical properties. It is also used as a research tool in the study of PAHs and their effects on human health and the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 243-24-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,4 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 243-24:
(5*2)+(4*4)+(3*3)+(2*2)+(1*4)=43
43 % 10 = 3
So 243-24-3 is a valid CAS Registry Number.
