α-Bis-(2,4-dichlor-5-fluorphenoxy)essigsaeure, also 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, as it mimics the action of natural plant hormones, causing uncontrolled growth and eventually leading to plant death. The herbicide is selective, meaning it affects certain plants while leaving others unharmed, making it a popular choice for crop protection. 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 impact on non-target organisms.
The CAS Registry Mumber 53145-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,4 and 5 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 53145-37: (7*5)+(6*3)+(5*1)+(4*4)+(3*5)+(2*3)+(1*7)=102 102 % 10 = 2 So 53145-37-2 is a valid CAS Registry Number.
