N-chloro-N-phenyl-toluene-4-sulfonamide, also known as chlorsulfuron, is a widely used herbicide belonging to the sulfonylurea class. It is effective in controlling various broadleaf and grassy weeds by inhibiting the enzyme acetohydroxyacid synthase, which is crucial for plant growth. This chemical is characterized by its white crystalline appearance and is soluble in organic solvents but has low solubility in water. Chlorsulfuron is applied pre-emergence and post-emergence, making it a versatile tool in agriculture. It is used in a variety of crops, including cereals and some fruit trees, to manage weed growth and improve crop yield. Due to its effectiveness and selectivity, chlorsulfuron is a valuable component in modern weed management strategies.

Check Digit Verification of cas no

The CAS Registry Mumber 2903-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2903-38:
(6*2)+(5*9)+(4*0)+(3*3)+(2*3)+(1*8)=80
80 % 10 = 0
So 2903-38-0 is a valid CAS Registry Number.
