It is a derivative of naphthalene and has two methoxy groups attached to the 2 and 4 positions of the naphthalene ring, as well as an aldehyde functional group at the 1 position. 2,4-Dimethoxy-naphthalene-1-carbaldehyde is often used as a building block in the synthesis of various organic compounds, including pharmaceuticals and agrochemicals. It is known for its aromatic and aldehydic odor and is considered to be a potentially hazardous chemical, with limited information available on its toxicological and environmental properties.
Check Digit Verification of cas no
The CAS Registry Mumber 75965-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,6 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75965-84:
(7*7)+(6*5)+(5*9)+(4*6)+(3*5)+(2*8)+(1*4)=183
183 % 10 = 3
So 75965-84-3 is a valid CAS Registry Number.

Manganese(III)-Mediated Formylation of Aromatic Compounds in the Presence of Malonic Acid
Nishino, Hiroshi,Tsunoda, Katsunori,Kurosawa, Kazu
, p. 545 - 550 (2007/10/02)
The reaction of naphthlenes with malonic acid in the presence of manganese(III) acetate gives naphthalenecarbaldehydes and naphthalenecarboxylic acids.Similar reactions of anthracene, pyrene, and methoxybenzenes also yield formylated and carboxylated products.It was found that the formyl group introduced to the aromatic ring was not derived from carboxymethyl radical generated directly by the thermolysis of manganese(III) acetate, but from a dicarboxymethyl radical formed by the interaction of malonic acid and manganese(III) acetate.In addition, it was also found that the dicarboxymethyl radicals attacked the position of the highest electron density on the aromatic ring and that this formylation was effective when the ionization potential of the aromatic copound was lower than 7.8 eV.
