Cycloheptyne is a cyclic alkyne with the molecular formula C7H10, consisting of a seven-membered carbon ring with a triple bond between two of the carbon atoms. It is an unsaturated hydrocarbon, which means it contains carbon-carbon triple bonds, making it highly reactive and prone to undergo various chemical reactions such as hydrogenation, halogenation, and addition reactions. Cycloheptyne is a colorless liquid with a pungent odor and is insoluble in water but soluble in organic solvents. Due to its reactivity, it is often used as a building block in the synthesis of more complex organic compounds and has potential applications in the pharmaceutical and chemical industries. However, it should be handled with caution due to its potential toxicity and flammability.
The CAS Registry Mumber 6577-09-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,7 and 7 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6577-09: (6*6)+(5*5)+(4*7)+(3*7)+(2*0)+(1*9)=119 119 % 10 = 9 So 6577-09-9 is a valid CAS Registry Number.
