2,2-dichloro-1,1-bis-(4-chloro-phenyl)-1-fluoro-ethane, also known as DDT, is a synthetic chemical compound that was widely used as an insecticide. It was first synthesized in 1874 by Othmar Zeidler and later rediscovered by Dr. Paul Müller in 1939, who recognized its effectiveness in controlling insects that spread diseases like malaria and typhus. DDT is characterized by its stable and persistent nature, which allowed it to be effective in killing a broad spectrum of insects. However, due to its persistence in the environment and its bioaccumulation in the food chain, leading to negative impacts on wildlife and potential health risks for humans, its use has been largely banned or restricted worldwide since the 1970s. Despite its historical importance in reducing the spread of vector-borne diseases, the environmental and health concerns associated with DDT have led to a shift towards safer alternatives in pest control.

3834-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3834-63-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.Calculate Digit Verification of CAS Registry Number 3834-63:
(6*3)+(5*8)+(4*3)+(3*4)+(2*6)+(1*3)=97
97 % 10 = 7
So 3834-63-7 is a valid CAS Registry Number.
