7-fluoro-1-phenylnaphthalene is an organic compound characterized by a naphthalene core, which is a fused ring system consisting of two benzene rings. One of the rings in 7-fluoro-1-phenylnaphthalene has a fluorine atom at the 7th position, and a phenyl group (a benzene ring) is attached to the 1st position. This molecule is a halogenated aromatic compound, which means it contains a halogen atom (in this case, fluorine) bonded to an aromatic ring. Such compounds are of interest in various fields, including pharmaceuticals and materials science, due to their unique electronic properties and potential applications in the synthesis of more complex molecules. The presence of the fluorine atom can significantly influence the compound's reactivity, stability, and interaction with other molecules, making it a subject of study in organic chemistry and medicinal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 2840-41-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2840-41:
(6*2)+(5*8)+(4*4)+(3*0)+(2*4)+(1*1)=77
77 % 10 = 7
So 2840-41-7 is a valid CAS Registry Number.

A new process for the [4 + 2] annulation of donor-acceptor cyclopropanes with acetylenes under the effect of anhydrous GaCl3 using 1,2-zwitterion reactivity was elaborated. The reaction opens access to substituted dihydronaphthalenes, naphthalenes, and other fused carbocycles. The direction of the reaction can be efficiently controlled by temperature.
