(2,4-Dichlor-3-hydroxy-phenoxy)-essigsaeure, also known as 2,4-dichlorophenoxyacetic acid (2,4-D), is a widely used synthetic auxin-type herbicide. It is an organic compound with the chemical formula C8H6Cl2O3, characterized by the presence of two chlorine atoms at the 2nd and 4th carbon positions, a hydroxyl group at the 3rd carbon position, and a carboxyl group at the end of the phenoxy chain. 2,4-D is effective in controlling broadleaf weeds and woody plants by mimicking the action of natural plant hormones, leading to uncontrolled growth and eventually plant death. It is commonly used in agriculture, forestry, and lawn care, but its application is regulated 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 2315-25-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,1 and 5 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2315-25: (6*2)+(5*3)+(4*1)+(3*5)+(2*2)+(1*5)=55 55 % 10 = 5 So 2315-25-5 is a valid CAS Registry Number.
