(3,5-dichloro-4-fluoro-phenoxy)-acetic acid, also known as 2,4-dichlorophenoxyacetic acid (2,4-D), is a widely used synthetic auxin-type herbicide. It is a chlorophenoxy herbicide that selectively controls broadleaf weeds and woody plants in various crops, such as cereals, corn, and pastures. The chemical structure consists of a dichloro-fluoro-phenoxy group attached to an acetic acid backbone, which allows it to mimic the action of natural plant hormones, leading to uncontrolled growth and ultimately the death of the targeted weeds. 2,4-D is known for its effectiveness in controlling weeds without harming the desired crops, making it a popular choice in agricultural applications. However, its use has also raised environmental and health concerns due to its potential impact on non-target organisms and persistence in the environment.

404-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 404-09-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.Calculate Digit Verification of CAS Registry Number 404-09:
(5*4)+(4*0)+(3*4)+(2*0)+(1*9)=41
41 % 10 = 1
So 404-09-1 is a valid CAS Registry Number.
