2-(3,4,5-Trimethyl-anilino)-naphthalin, also known as 2-(3,4,5-trimethylphenylamino)naphthalene, is an organic compound with the chemical formula C19H19N. It is a derivative of naphthalene, featuring a naphthalene core with an aniline group attached at the 2-position. The aniline group itself is a substituted phenylamine, where the phenyl ring is further substituted with three methyl groups at the 3, 4, and 5 positions. 2-<3,4,5-Trimethyl-anilino>-naphthalin is characterized by its aromatic nature and may exhibit various chemical properties due to the presence of both the naphthalene and aniline moieties. It is typically synthesized for use in chemical research and as an intermediate in the production of certain dyes and pigments, given its potential to form complexes or participate in various chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 1639-29-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1639-29:
(6*1)+(5*6)+(4*3)+(3*9)+(2*2)+(1*9)=88
88 % 10 = 8
So 1639-29-8 is a valid CAS Registry Number.
