13256-69-4 Usage
General Description
1-(2-chlorophenyl)-3-(4-methylphenyl)urea is a chemical compound that is also known as diuron. It is a white, crystalline solid that is commonly used as an herbicide to control the growth of weeds in agricultural and non-agricultural areas. Diuron works by inhibiting photosynthesis in the target plants, leading to their eventual death. It is considered to be relatively low in toxicity to mammals, but it can have harmful effects on aquatic life and other non-target organisms if it enters water bodies. Diuron has been registered for use in various countries around the world, but its use is subject to regulations and restrictions to minimize its environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 13256-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,5 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13256-69:
(7*1)+(6*3)+(5*2)+(4*5)+(3*6)+(2*6)+(1*9)=94
94 % 10 = 4
So 13256-69-4 is a valid CAS Registry Number.
