2-Hydroxy-5,6-dimethylcyclohexa-2,5-diene-1,4-dione, also known as juglone, is a chemical compound derived from the breakdown of the enzyme polyphenol oxidase in plants. It is a naturally occurring organic compound with a molecular formula of C10H8O4 and a molecular weight of 192.17 g/mol. Juglone is a dark purple pigment found in the heartwood and bark of the black walnut tree (Juglans nigra) and other plants in the Juglandaceae family. It has a characteristic chemical structure, featuring a cyclohexadiene ring with a hydroxyl group at the 2-position, two methyl groups at the 5 and 6 positions, and a 1,4-dione group. Juglone exhibits various biological activities, such as antifungal, antibacterial, and cytotoxic properties, and has been used in traditional medicine and as a natural dye. However, it is also known for its allelopathic effects, inhibiting the growth of other plants in its vicinity.

1760-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1760-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1760-68:
(6*1)+(5*7)+(4*6)+(3*0)+(2*6)+(1*8)=85
85 % 10 = 5
So 1760-68-5 is a valid CAS Registry Number.
