Propanoic acid, 3-(2,5-dichlorophenoxy)-, also known as 2,5-dichlorophenoxypropanoic acid or 2,5-Dichlorophenoxypropionic acid, is a synthetic auxin-type herbicide. It is a white crystalline solid with the chemical formula C9H8Cl2O3. Propanoic acid, 3-(2,5-dichlorophenoxy)- is widely used in agriculture to control broadleaf weeds and woody plants by mimicking the action of natural plant hormones, which leads to uncontrolled growth and ultimately the death of the plant. It is particularly effective in controlling weeds in cereal crops and has been a component in various herbicide formulations. However, due to its potential environmental and health concerns, its use has been restricted or banned in some regions.

7170-68-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7170-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,7 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7170-68:
(6*7)+(5*1)+(4*7)+(3*0)+(2*6)+(1*8)=95
95 % 10 = 5
So 7170-68-5 is a valid CAS Registry Number.
