2,4-dichlorophenoxyacetic acid, commonly known as 2,4-D, is a widely used synthetic auxin-type herbicide that belongs to the chlorophenoxy family. It is primarily used to control broadleaf weeds and woody plants in agricultural fields, lawns, and gardens. 2,4-D works by mimicking the action of natural plant hormones, causing uncontrolled growth and eventually leading to the death of the targeted weeds. The chemical structure of 2,4-D consists of a 2,4-dichlorophenoxy group attached to an acetic acid moiety. It is known for its selective herbicidal properties, as it can be applied to certain crops without causing significant damage to them, while effectively controlling unwanted vegetation. However, its use has been a subject of debate due to potential environmental and health concerns, including its persistence in soil and water, as well as its potential to disrupt the endocrine system in humans and animals.
The CAS Registry Mumber 3209-10-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 9 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3209-10: (6*3)+(5*2)+(4*0)+(3*9)+(2*1)+(1*0)=57 57 % 10 = 7 So 3209-10-7 is a valid CAS Registry Number.
