Cyclohexadeca-1,3,9,11-tetrayne is a polyyne hydrocarbon with the molecular formula C16H8. It consists of a linear chain of 16 carbon atoms, with four carbon-carbon triple bonds (acetylenic linkages) at positions 1, 3, 9, and 11, separated by single bonds. This molecule is known for its rigid structure and unique electronic properties, which arise from the conjugation of the triple bonds. It is a challenging synthetic target due to its instability and sensitivity to various reaction conditions. Cyclohexadeca-1,3,9,11-tetrayne has been studied for its potential applications in materials science and as a model compound for understanding the behavior of polyynes, which are of interest in astrochemistry and organic electronics.

Check Digit Verification of cas no

The CAS Registry Mumber 4634-66-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4634-66:
(6*4)+(5*6)+(4*3)+(3*4)+(2*6)+(1*6)=96
96 % 10 = 6
So 4634-66-6 is a valid CAS Registry Number.
