ω-<4.5-Dichlor-2-methoxy-phenoxy>-acetoveratron, also known as 2,4-dichlorophenoxyacetic acid (2,4-D), is a widely used synthetic auxin-type herbicide. It is a chlorophenoxy compound with the chemical formula C8H6Cl2O3. 2,4-D is primarily used to control broadleaf weeds and woody plants in agricultural fields, lawns, and gardens. It works by mimicking the action of natural plant hormones, causing uncontrolled growth and eventually leading to the death of the targeted plants. The herbicide is selective, meaning it affects certain plants while leaving others unharmed, making it a valuable tool in crop management. 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 impact on non-target organisms.
The CAS Registry Mumber 93313-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 93313-89: (7*9)+(6*3)+(5*3)+(4*1)+(3*3)+(2*8)+(1*9)=134 134 % 10 = 4 So 93313-89-4 is a valid CAS Registry Number.
