7-Methylidenecyclohepta-1,3,5-triene is a chemical compound with the molecular formula C8H8. It is a conjugated diene, which means it has alternating double and single bonds in its structure. The compound features a seven-membered ring with a methylidene group (a carbon atom double-bonded to a hydrogen atom) at the 7-position. This structure gives the molecule unique chemical properties and reactivity, such as its ability to participate in Diels-Alder reactions, which are important in organic synthesis. The compound is also known for its aromatic character, which arises from the delocalization of π electrons across the ring. This aromaticity contributes to the stability and unique chemical behavior of 7-methylidenecyclohepta-1,3,5-triene.

Check Digit Verification of cas no

The CAS Registry Mumber 539-79-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 539-79:
(5*5)+(4*3)+(3*9)+(2*7)+(1*9)=87
87 % 10 = 7
So 539-79-7 is a valid CAS Registry Number.
