2-(2,4-Dinitro-phenylsulfanyl)-4-ethoxy-6-nitro-phenylamine is a complex organic compound with the molecular formula C14H12N4O7S. It is characterized by the presence of two nitro groups (NO2), an ethoxy group (C2H5O), and a phenylsulfanyl group (S-Ph). The compound features a phenylamine structure, which is a benzene ring with an amino group attached. The 2,4-dinitro-phenylsulfanyl group is attached to the 2-position of the phenylamine, while the 4-ethoxy group is attached to the 4-position, and the 6-nitro group is attached to the 6-position. 2-(2,4-Dinitro-phenylsulfanyl)-4-ethoxy-6-nitro-phenylamine is likely to be used in chemical research or as an intermediate in the synthesis of other compounds, given its complex structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 74834-83-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,3 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74834-83:
(7*7)+(6*4)+(5*8)+(4*3)+(3*4)+(2*8)+(1*3)=156
156 % 10 = 6
So 74834-83-6 is a valid CAS Registry Number.

Studies on phenothiazines, Part 6. Synthesis of 3-alkoxy-1-nitro-7-substituted phenothiazines via Smiles rearrangement

Gupta, R.R.,Jain, S.K.,Goswami, Naresh K.,Kalwania, G.S.

, p. 831 - 836 (2007/10/02)

Synthesis of 3-alkoxy-1-nitro-7-substituted phenothiazines via Smiles rearrangement is reported. 5-Alkoxy-2-amino-3-nitro benzenethiols prepared by hydrolytic fission of 6-alkoxy-4-nitrobenzo-1,2,3-dithiazolium chloride (The Herz Compound) were condensed with substituted o-chloro-nitrobenzenes and the diaryl sulfides so obtained were converted into formyl derivatives by formic acid.The latter on treatment with alkoholic KOH underwent Smiles rearrangement yielding 3-alkoxy-1-nitro-7-substituted phenothiazines.
