Cyclooctadeca-1,3,7,9,13,15-hexayne is a complex organic compound characterized by its unique structure, consisting of an 18-carbon cyclic backbone with six carbon-carbon triple bonds (acetylenic linkages) at alternating positions. This molecule is highly unsaturated, with a total of 12 pi electrons distributed across its triple bonds. Due to its rigid cyclic structure and extensive conjugation, it exhibits interesting electronic and optical properties, making it a subject of interest in the field of materials science and organic chemistry. The compound's name is derived from its molecular formula, indicating the presence of a cycloalkane ring with 18 carbon atoms and six acetylenic linkages.
The CAS Registry Mumber 7092-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 7092-39: (6*7)+(5*0)+(4*9)+(3*2)+(2*3)+(1*9)=99 99 % 10 = 9 So 7092-39-9 is a valid CAS Registry Number.
