1-Naphthalenecarboxaldehyde, 2,4-dihydroxy-, also known as 2,4-dihydroxy-1-naphthaldehyde or juglone, is a naturally occurring organic compound with the chemical formula C11H8O3. It is a yellow crystalline solid that is derived from the oxidation of the hydroquinone component of natural compounds found in the heartwood and bark of the black walnut tree (Juglans nigra). Juglone has various applications, including its use as a laxative, an antihelmintic, and a dye. It is also known for its antimicrobial, antifungal, and cytotoxic properties, which can be utilized in the development of pharmaceuticals and pesticides. However, it is important to note that juglone can be toxic to certain plants, making it a potential allelopathic agent in plant competition.

The CAS Registry Mumber 2089-78-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 2089-78:
(6*2)+(5*0)+(4*8)+(3*9)+(2*7)+(1*8)=93
93 % 10 = 3
So 2089-78-3 is a valid CAS Registry Number.
