83-80-7 Usage
General Description
1,5-dibenzoylnaphthalene is a chemical compound that is a derivative of naphthalene, consisting of two benzoyl groups attached to the 1 and 5 positions of the naphthalene ring. It is often used as a reagent in organic synthesis and as a starting material in the production of dyes, pigments, and other organic compounds. 1,5-dibenzoylnaphthalene is known for its ability to undergo various chemical reactions such as Friedel-Crafts acylation and nucleophilic substitution, making it a versatile building block in the field of organic chemistry. Additionally, it is also used in research and pharmaceutical industries for the synthesis of new pharmaceutical compounds and other functional materials.
Check Digit Verification of cas no
The CAS Registry Mumber 83-80-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83-80:
(4*8)+(3*3)+(2*8)+(1*0)=57
57 % 10 = 7
So 83-80-7 is a valid CAS Registry Number.

Incorporation of the 1,5-naphthalene subunit into heteroporphyrin structure: Toward helical aceneporphyrinoids

5,10,15,20-Tetraaryl-22-hetero-1,5-naphthiporphyrins, which contain a 1,5-naphthylene moiety instead of one pyrrole embedded in the macrocyclic framework of heteroporphyrins, were obtained by the [3 + 1] approach using the 1,5-naphthylene analogue of tripyrrane (1,5-bis(phenyl(2-pyrolyl)methyl) naphthalene) and 2,5-bis(arylhydroxymethyl)heterocyclopentadiene (heterocyclopentadiene: thiophene, selenophene, tellurophene). The steric constraints, imposed by the substitution mode of the 1,5-naphthylene building block, resulted in the specific helical conformation of 22-hetero-1,5- naphthiporphyrins. The spectroscopic and structural properties of these aceneporphyrinoids indicate a lack of macrocycle aromaticity. Their protonation yielded solely dicationic species.
