1143-11-9 Usage
General Description
2,3,5,6,8-Pentahydroxy-1,4-naphthoquinone, also known as juglone, is a naturally occurring organic compound found in many plants, including walnut trees. It is a distinctive dark yellow crystalline solid that has antifungal and allelopathic properties, meaning it can inhibit the growth of fungi and other plants. Juglone is widely used in traditional and modern medicine due to its antimicrobial and anti-inflammatory properties. Additionally, it has been found to have potential anticancer and antioxidant activities. However, juglone can also be toxic to certain organisms, and excessive exposure to it can cause skin irritation and other adverse effects.

Check Digit Verification of cas no
The CAS Registry Mumber 1143-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1143-11:
(6*1)+(5*1)+(4*4)+(3*3)+(2*1)+(1*1)=39
39 % 10 = 9
So 1143-11-9 is a valid CAS Registry Number.

Synthesis of Spinochrome D, A Metabolite of Various Sea-Urchin Species
Balaneva,Shestak,Anufriev,Novikov
, p. 213 - 217 (2016)
The sea-urchin metabolite spinochrome D (1) was synthesized in 58% overall yield via oxidation of 2,3-dichloronaphthazarin (13) into 2-hydroxy-6,7-dichloronaphthazarin (14), O-methylation of 14, nucleophilic substitution by MeO groups of the Cl atoms in the resulting 2-methoxy-6,7-dichloronaphthazarin (19), and hydrolysis of the obtained 2,3,6-trimethoxynaphthazarin (10).
