1,4-Naphthalenedione, 2-(4-aminophenyl)-, also known as 2-(4-aminophenyl)-1,4-naphthoquinone or Lawsone, is an organic compound with the chemical formula C15H11NO2. It is a yellow crystalline substance that is soluble in ethanol, ether, and chloroform. Lawsone is derived from the henna plant (Lawsonia inermis) and is used as a natural dye, particularly for hair and skin. It has been traditionally used in henna tattoos and as a coloring agent in various cosmetic and food products. The compound exhibits antioxidant properties and has been studied for its potential therapeutic applications, including anti-inflammatory and anticancer effects. However, it is important to note that the safety and efficacy of Lawsone in these applications are still under investigation, and it should be used with caution.

Check Digit Verification of cas no

The CAS Registry Mumber 87872-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,7 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87872-29:
(7*8)+(6*7)+(5*8)+(4*7)+(3*2)+(2*2)+(1*9)=185
185 % 10 = 5
So 87872-29-5 is a valid CAS Registry Number.
