2,3,5-trichlorophenylacetic acid is a synthetic chemical compound with the molecular formula C8H5Cl3O2. It is a derivative of phenylacetic acid, where three chlorine atoms are substituted at the 2nd, 3rd, and 5th positions on the benzene ring. 2,3,5-trichlorophenylacetic acid is primarily used as a plant growth regulator and a defoliant in agriculture, particularly for cotton crops. It promotes the shedding of leaves and bolls, which can improve the efficiency of mechanical harvesting and reduce the risk of contamination from leaves and other plant material. However, due to its potential environmental and health concerns, its use has been restricted or banned in several countries.

4681-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4681-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,8 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4681-13:
(6*4)+(5*6)+(4*8)+(3*1)+(2*1)+(1*3)=94
94 % 10 = 4
So 4681-13-4 is a valid CAS Registry Number.
