N-n-propyl-N'-cyano-s-methylisothiourea, also known as NPTU, is a chemical compound with the molecular formula C6H12N4S. It is a white crystalline solid that is primarily used as a herbicide to control broadleaf and grassy weeds in various crops, including soybeans, cotton, and peanuts. NPTU works by inhibiting the enzyme acetolactate synthase, which is essential for the synthesis of branched-chain amino acids in plants, ultimately leading to the cessation of plant growth and death. Due to its effectiveness and low toxicity to mammals, NPTU has been widely used in agriculture. However, it is important to follow proper application guidelines and safety measures to minimize potential environmental and health risks.
The CAS Registry Mumber 5848-26-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 8 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5848-26: (6*5)+(5*8)+(4*4)+(3*8)+(2*2)+(1*6)=120 120 % 10 = 0 So 5848-26-0 is a valid CAS Registry Number.
