1-Formyl-7-bromonaphthalene is an organic compound characterized by a naphthalene core, which is a fused ring system consisting of two benzene rings. This particular compound has a bromine atom attached at the 7th position and a formyl group (an aldehyde functional group, -CHO) at the 1st position. The presence of the bromine atom introduces halogenation, which can significantly alter the chemical reactivity and physical properties of the molecule compared to its non-brominated counterparts. The formyl group provides a site for further chemical reactions, such as reduction to an alcohol or oxidation to a carboxylic acid. 1-formyl-7-bromonaphthalene is often used as an intermediate in the synthesis of more complex organic molecules, particularly in the pharmaceutical and chemical industries, due to its reactivity and the ability to be further functionalized.

Check Digit Verification of cas no

The CAS Registry Mumber 81830-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,3 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81830-59:
(7*8)+(6*1)+(5*8)+(4*3)+(3*0)+(2*5)+(1*9)=133
133 % 10 = 3
So 81830-59-3 is a valid CAS Registry Number.
