Uses
Used in Agriculture and Horticulture:
4-Chloro-6-(MethoxyMethyl)-2-MethylpyriMidine is used as a pre-emergent herbicide for controlling grasses and broadleaf weeds in various crops. It functions by inhibiting the biosynthesis of carotenoids, which are essential pigments for photosynthesis in plants, ultimately leading to the death of the targeted weeds. This helps preserve crop yield and maintain the quality of agricultural and horticultural products.
The use of Clomazone as a herbicide is favored due to its low acute toxicity to mammals, ensuring the safety of humans and animals in the surrounding environment. Additionally, its relatively low environmental persistence minimizes the potential for long-term ecological impact, making it a preferred choice for sustainable agricultural practices.
Check Digit Verification of cas no
The CAS Registry Mumber 3122-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3122-81:
(6*3)+(5*1)+(4*2)+(3*2)+(2*8)+(1*1)=54
54 % 10 = 4
So 3122-81-4 is a valid CAS Registry Number.
