1,4-Naphthalenedione, 2-(1,5-dioxohexyl)-8-methoxy-, also known as Lawsone, is a naturally occurring chemical compound derived from the henna plant (Lawsonia inermis). It is a yellow crystalline substance with a molecular formula of C15H14O5 and a molecular weight of 270.27 g/mol. Lawsone is a key component responsible for the color and dyeing properties of henna, and it is used in various applications, including hair dyeing, skin staining, and as a natural colorant in the food and cosmetic industries. The compound exhibits a unique chemical structure, featuring a naphthalene core with a diketone group at the 1,4-positions, a methoxy group at the 8-position, and a 1,5-dioxohexyl chain attached to the 2-position. Due to its natural origin and potential health benefits, Lawsone has gained significant interest in recent years for its potential use in pharmaceutical and cosmetic products.

Check Digit Verification of cas no
The CAS Registry Mumber 95455-94-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,4,5 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 95455-94:
(7*9)+(6*5)+(5*4)+(4*5)+(3*5)+(2*9)+(1*4)=170
170 % 10 = 0
So 95455-94-0 is a valid CAS Registry Number.
