1,2,2-trichloro-1,1-bis-(4-chloro-phenyl)-ethane, commonly known as DDT, is a synthetic organochlorine compound historically used as an insecticide. It was first synthesized in 1874 but gained prominence in the 1940s for its effectiveness in controlling mosquitoes and preventing the spread of diseases like malaria. DDT is characterized by its stable chemical structure, which allows it to persist in the environment for long periods, leading to bioaccumulation in the food chain. This persistence, along with its toxicity to non-target organisms, including birds and aquatic life, has resulted in its ban or restriction in many countries due to environmental and health concerns. Despite its initial benefits, the long-term impacts of DDT on ecosystems have led to a reevaluation of its use, highlighting the importance of considering the environmental consequences of chemical pesticides.

4681-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4681-97-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,8 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4681-97:
(6*4)+(5*6)+(4*8)+(3*1)+(2*9)+(1*7)=114
114 % 10 = 4
So 4681-97-4 is a valid CAS Registry Number.
