1,4-Naphthalenedione, 2-hydroxy-5-methoxy-, also known as juglone or 5-hydroxy-1,4-naphthoquinone, is a naturally occurring organic compound with the chemical formula C10H8O3. It is a dark purple crystalline solid that is soluble in water, alcohol, and ether. Juglone is primarily found in the heartwood, leaves, and bark of the black walnut tree (Juglans nigra) and is responsible for the tree's allelopathic properties, which inhibit the growth of other plants. 1,4-Naphthalenedione, 2-hydroxy-5-methoxy- has various applications, including its use as a natural dye, a chemical intermediate in the synthesis of other compounds, and in traditional medicine for its antifungal, antibacterial, and anti-inflammatory properties. However, it is also known for its potential toxicity and should be handled with caution.

71186-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71186-96-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,8 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.Calculate Digit Verification of CAS Registry Number 71186-96:
(7*7)+(6*1)+(5*1)+(4*8)+(3*6)+(2*9)+(1*6)=134
134 % 10 = 4
So 71186-96-4 is a valid CAS Registry Number.
