Picene, also known as 1,2,3,4-tetrahydro-2,2,9-trimethyl, is a polycyclic aromatic hydrocarbon (PAH) with a molecular formula of C21H18. It is a naturally occurring compound found in various environments, such as coal tar, crude oil, and even in some meteorites. Picene has a unique structure consisting of five fused benzene rings, with two methyl groups attached to the second and ninth carbon atoms, and a saturated four-membered ring in the center. Due to its complex structure, picene exhibits interesting optical and electronic properties, making it a subject of interest in the fields of materials science and organic chemistry. However, like other PAHs, picene is also considered to be potentially harmful to human health and the environment, as it can contribute to the formation of air pollution and has been classified as a carcinogenic substance.

1242-76-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1242-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1242-76:
(6*1)+(5*2)+(4*4)+(3*2)+(2*7)+(1*6)=58
58 % 10 = 8
So 1242-76-8 is a valid CAS Registry Number.
