1,1,1,2,2-pentachloro-3,3-diphenyl-propane, commonly known as DDT, is a synthetic chemical compound that was widely used as an insecticide during the mid-20th century. It was first synthesized in 1874 by Othmar Zeidler and later rediscovered by Dr. Paul Müller in 1939, who recognized its effectiveness as an insecticide and was awarded the Nobel Prize for his discovery. DDT is characterized by its ability to kill insects by interfering with their nervous systems, making it highly effective in controlling the spread of diseases such as malaria. However, due to its persistence in the environment, bioaccumulation in the food chain, and potential harmful effects on non-target organisms, including humans, DDT has been banned or restricted in many countries since the 1970s. Despite its historical significance in public health, the long-term environmental and health concerns associated with DDT have led to its decline in use and the search for safer alternatives in pest control.

843-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 843-87-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 843-87:
(5*8)+(4*4)+(3*3)+(2*8)+(1*7)=88
88 % 10 = 8
So 843-87-8 is a valid CAS Registry Number.
