General Description

2,3,4,5-Tetrachloro-6-[(4-hydroxyphenyl)(4-oxocyclohexa-2,5-dien-1-ylidene)methyl]benzoic acid is a chemical compound with the molecular formula C19H10Cl4O4. It is a derivative of benzoic acid and contains four chlorine atoms, a hydroxyphenyl group, and a cyclohexa-2,5-dien-1-ylidene methyl group. 2,3,4,5-Tetrachloro-6-[(4-hydroxyphenyl)(4-oxocyclohexa-2,5-dien-1-ylidene)methyl]benzoic acid is commonly used as a pesticide and herbicide, particularly for controlling broadleaf weeds and woody plants. It works by disrupting photosynthesis in the target plants, leading to their eventual death. However, due to its toxic nature and potential environmental and health risks, its use has been heavily restricted or banned in many countries. Additionally, exposure to this compound has been linked to various health issues in humans and animals, making it important to handle and use it with caution.

Check Digit Verification of cas no

The CAS Registry Mumber 128-74-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128-74:
(5*1)+(4*2)+(3*8)+(2*7)+(1*4)=55
55 % 10 = 5
So 128-74-5 is a valid CAS Registry Number.
