1,1-Dichloro-2,2-bis-(4-iodo-phenyl)-ethane, also known as DDD or TDE, is an organochlorine compound that belongs to the class of halogenated hydrocarbons. It is a synthetic chemical compound with the molecular formula C14H10Cl2I2. DDD was historically used as an insecticide and as a component in anti-fouling paints. It is a white crystalline solid with low solubility in water and high solubility in organic solvents. Due to its persistence in the environment and potential health risks, including endocrine disruption and neurotoxicity, the use of DDD has been largely phased out or banned in many countries. It is important to note that DDD should not be confused with DDT, another organochlorine pesticide with different chemical properties and uses.

5121-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5121-69-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,2 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 5121-69:
(6*5)+(5*1)+(4*2)+(3*1)+(2*6)+(1*9)=67
67 % 10 = 7
So 5121-69-7 is a valid CAS Registry Number.
