1,4-Naphthalenedione, 2,3,5,7-tetramethoxy-, also known as Lawsone or Henna, is a naturally occurring organic compound derived from the henna plant (Lawsonia inermis). It is a yellow crystalline substance with a molecular formula of C12H12O6 and a molecular weight of 252.22 g/mol. Lawsone is a key component responsible for the color and dyeing properties of henna, which has been used for centuries in various cultural practices, such as body art and hair dyeing. The compound exhibits a strong affinity for proteins, allowing it to bind effectively to keratin in hair and skin, resulting in a reddish-brown color. Additionally, it has been studied for its potential antimicrobial, antifungal, and antioxidant properties, making it a subject of interest in the fields of cosmetics, pharmaceuticals, and traditional medicine.

Check Digit Verification of cas no

The CAS Registry Mumber 65565-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,6 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65565-44:
(7*6)+(6*5)+(5*5)+(4*6)+(3*5)+(2*4)+(1*4)=148
148 % 10 = 8
So 65565-44-8 is a valid CAS Registry Number.
