129-37-3 Usage
General Description
9,10-dihydro-8-nitro-9,10-dioxoanthracene-1-sulphonic acid is a chemical compound with the molecular formula C14H9NO7S. It is a synthetic derivative of anthracene and is commonly used in the production of dyes and pigments. 9,10-dihydro-8-nitro-9,10-dioxoanthracene-1-sulphonic acid is a sulfonic acid, which means it contains a sulfur atom bonded to three oxygen atoms and is highly water-soluble. It is often used in the manufacturing of acid dyes, which are commonly applied to wool and silk fabrics. The presence of the nitro group in the molecule gives it a yellow to red color, making it useful for creating a range of vibrant dyes. Additionally, its sulfonic acid group makes it highly reactive and easily reactive with other chemicals, allowing for the production of a variety of different dye colors.
Check Digit Verification of cas no
The CAS Registry Mumber 129-37-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129-37:
(5*1)+(4*2)+(3*9)+(2*3)+(1*7)=53
53 % 10 = 3
So 129-37-3 is a valid CAS Registry Number.

Synthesis and cytotoxic activity of 7-oxo-7H-dibenz[f,ij]isoquinoline and 7-oxo-7H-benzo[e]perimidine derivatives

, p. 2004 - 2014 (2007/10/03)
A series of 7-oxo-7H-dibenz[f,ij]isoquinoline and 7-oxo-7H-benzo[e]perimidines bearing cationic side chains were prepared from aminoanthraquinones. The perimidines were prepared from 1-aminoanthraquinone by initial condensation with urea or dimethylacetamide. A series of 2-, 4-, 8-, and 11-carboxy derivatives of the dibenzisoquinolines were prepared from aminoanthraquinonecarboxylic acids. The cationic derivatives were prepared from these via amide, amine, or methylene linkers to study the effects of side chain positioning on biological activity. Within the series of carboxamide-linked compounds, the order of increasing cytotoxicity was 8- 4- 2- 11-. The 2- and 4-carboxamides showed substantial growth delays against in vivo subcutaneous colon 38 tumors in mice, but the 11-carboxamide had curative activity in this refractory model and is being investigated further.
