C24H22 is an organic compound with the molecular formula C24H22, which consists of 24 carbon atoms and 22 hydrogen atoms. C24H22 belongs to the class of polycyclic aromatic hydrocarbons (PAHs), which are known for their complex ring structures and potential environmental and health impacts. PAHs are formed during the incomplete combustion of organic materials and can be found in various environmental settings, including air, water, and soil. They are also associated with the production of certain industrial chemicals and can be released into the environment through various processes. Due to their potential carcinogenic properties, there is significant interest in understanding their formation, distribution, and effects on human health and the environment.
The CAS Registry Mumber 2202-73-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2202-73: (6*2)+(5*2)+(4*0)+(3*2)+(2*7)+(1*3)=45 45 % 10 = 5 So 2202-73-5 is a valid CAS Registry Number.
