2-(2,4-dichlorophenoxy)-N-(3,4-dichlorophenyl)acetamide, commonly known as 2,4-Dichlorophenoxyacetic acid (2,4-D), is a widely used synthetic auxin-type herbicide. It is a white crystalline solid with the chemical formula C8H6Cl2O3. 2,4-D is primarily used to control broadleaf weeds and woody plants in agricultural fields, lawns, and gardens by mimicking the action of natural plant hormones, leading to uncontrolled growth and eventually plant death. It was first synthesized in 1942 and has since become one of the most widely used herbicides globally. However, its use has been a subject of controversy due to potential environmental and health risks, including endocrine disruption and aquatic ecosystem impacts. Despite these concerns, 2,4-D remains a popular choice for weed control due to its effectiveness and relatively low cost.

Check Digit Verification of cas no
The CAS Registry Mumber 7620-18-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.Calculate Digit Verification of CAS Registry Number 7620-18:
(6*7)+(5*6)+(4*2)+(3*0)+(2*1)+(1*8)=90
90 % 10 = 0
So 7620-18-0 is a valid CAS Registry Number.
