9-Methyl-1,2,3,4,9,10-hexahydro-phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C17H18. It is a derivative of phenanthrene, which is a three-ring structure consisting of two benzene rings fused to a third ring. The "9-methyl" part of the name indicates that there is a methyl group (CH3) attached to the ninth carbon atom in the molecule. 9-methyl-1,2,3,4,9,10-hexahydro-phenanthrene is a member of the hexahydro-phenanthrene family, which means that it has six hydrogen atoms added to the phenanthrene structure, making it partially saturated. 9-Methyl-1,2,3,4,9,10-hexahydro-phenanthrene is an organic compound that can be found in various environmental sources, such as coal tar and petroleum products. It is also a component of some natural products, like certain types of coal and crude oil. Due to its complex structure and potential environmental impact, research on 9-methyl-1,2,3,4,9,10-hexahydro-phenanthrene focuses on its formation, properties, and potential health effects.
The CAS Registry Mumber 1634-08-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 4 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1634-08: (6*1)+(5*6)+(4*3)+(3*4)+(2*0)+(1*8)=68 68 % 10 = 8 So 1634-08-8 is a valid CAS Registry Number.
