Tomanol, also known as 2-(2,4,5-trichlorophenoxy)propionic acid, is a synthetic auxin herbicide that was widely used in the past for controlling broadleaf weeds and woody plants. It is a white crystalline solid with a chemical formula of C9H7Cl3O3. Tomanol was primarily used in agriculture and forestry to promote growth and control unwanted vegetation. However, due to its potential environmental and health risks, including persistence in soil and water, as well as its ability to disrupt the endocrine system in humans and animals, its use has been restricted or banned in many countries. As a result, Tomanol has been largely phased out in favor of safer and more environmentally friendly alternatives.
The CAS Registry Mumber 8058-14-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,5 and 8 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 8058-14: (6*8)+(5*0)+(4*5)+(3*8)+(2*1)+(1*4)=98 98 % 10 = 8 So 8058-14-8 is a valid CAS Registry Number.
