21081-74-3 Usage
General Description
1-chloro-2-(methylsulphonyl)-4-nitrobenzene, also known as Meosulfuron-methyl, is a chemical compound used as an herbicide for the control of broadleaf and grassy weeds in various crops. It is a member of the sulfonylurea family of herbicides and works by inhibiting the activity of acetolactate synthase, an enzyme involved in the biosynthesis of the branched-chain amino acids isoleucine, leucine, and valine. This disruption in the synthesis of essential amino acids ultimately leads to the death of the targeted weeds. Meosulfuron-methyl is considered to have a low acute toxicity to mammals and has shown to be effective in controlling a wide range of resistant weed species. However, it is important to follow strict safety guidelines and regulations when handling and applying this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 21081-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,8 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21081-74:
(7*2)+(6*1)+(5*0)+(4*8)+(3*1)+(2*7)+(1*4)=73
73 % 10 = 3
So 21081-74-3 is a valid CAS Registry Number.
