The chemical compound "(3aS)-3c,7,7-trimethyl-(8ac)-octahydro-3ar,6c-methano-azulen-8-one" is a complex organic molecule with a unique structure. It is characterized by its octahydroazulene framework, which is a type of cyclic hydrocarbon with eight carbon atoms. The compound features three methyl groups at positions 3, 7, and 7, contributing to its branched structure. The "3aS" and "8ac" notations indicate the specific stereochemistry of the molecule, with "S" denoting the absolute configuration at the 3a position and "ac" specifying the arrangement of the atoms at the 8a position. The "methano" prefix suggests the presence of a methylene bridge (-CH2-) within the molecule, which connects two parts of the structure. The "8-one" ending indicates the presence of a carbonyl group (C=O) at the 8 position, which is a key functional group in many organic compounds. (3aS)-3c,7,7-trimethyl-(8ac)-octahydro-3ar,6c-methano-azulen-8-one is a derivative of azulen, a type of sesquiterpene, and its specific arrangement of atoms and functional groups give it distinct chemical properties and potential applications in various fields, such as pharmaceuticals or materials science.
The CAS Registry Mumber 18045-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,4 and 5 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 18045-55: (7*1)+(6*8)+(5*0)+(4*4)+(3*5)+(2*5)+(1*5)=101 101 % 10 = 1 So 18045-55-1 is a valid CAS Registry Number.
