1,4-Naphthalenedione, 2-(1-pyrrolidinyl)-, also known as 2-(1-Pyrrolidinyl)-1,4-naphthoquinone or Lawsone, is a naturally occurring chemical compound derived from the henna plant (Lawsonia inermis). It is a yellow crystalline solid with a molecular formula of C11H9NO2 and a molecular weight of 189.19 g/mol. Lawsone is known for its various applications, including its use as a natural dye, a food additive, and a potential chemopreventive agent due to its antioxidant and anti-inflammatory properties. The compound exhibits a strong affinity for proteins, which is responsible for the temporary reddish-brown coloration of the skin when henna is applied. Additionally, it has been studied for its potential anti-cancer properties, as it can induce apoptosis in certain cancer cells.

59641-26-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 59641-26-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,6,4 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 59641-26:
(7*5)+(6*9)+(5*6)+(4*4)+(3*1)+(2*2)+(1*6)=148
148 % 10 = 8
So 59641-26-8 is a valid CAS Registry Number.
