General Description
2,2,2-trichloro-N-(5-methyl-1,3,4-thiadiazol-2-yl)acetamide is a synthetic organic compound with the chemical formula C5H5Cl3N4O. It is a chloroacetamide herbicide that is used to control grass and broadleaf weeds in various crops. The compound works by inhibiting the enzyme acetohydroxyacid synthase (AHAS) in plants, which is essential for the biosynthesis of branched-chain amino acids. This inhibition leads to the death of the treated weeds. 2,2,2-trichloro-N-(5-methyl-1,3,4-thiadiazol-2-yl)acetamide is considered to have low toxicity to humans and animals when used according to the label instructions, but it can be harmful if ingested or absorbed through the skin in high amounts.
Check Digit Verification of cas no
The CAS Registry Mumber 21521-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21521-89:
(7*2)+(6*1)+(5*5)+(4*2)+(3*1)+(2*8)+(1*9)=81
81 % 10 = 1
So 21521-89-1 is a valid CAS Registry Number.
