558-57-6 Usage
General Description
1,2-Dibromo-1,1-dichloro-2,2-dichloroethane, also known as DBDCD, is a highly toxic and environmentally persistent chemical compound. It was previously used as a pesticide and fumigant, but its production and use have been largely discontinued due to its harmful effects on human health and the environment. Exposure to DBDCD can cause skin irritation, respiratory problems, and damage to the liver and kidneys. It is also a known carcinogen and can bioaccumulate in the environment, posing a risk to aquatic organisms and non-target species. Due to its hazardous nature, there are strict regulations and restrictions on the use and disposal of DBDCD, and it is classified as a hazardous waste.
Check Digit Verification of cas no
The CAS Registry Mumber 558-57-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 558-57:
(5*5)+(4*5)+(3*8)+(2*5)+(1*7)=86
86 % 10 = 6
So 558-57-6 is a valid CAS Registry Number.

Method for preparing bromodifluoroacetic compounds
-
, (2008/06/13)
The invention relates to a method for preparing bromodifluoroacetic compounds which comprises converting a 1,1-diflouro-1,2-dibromodihaloethane with oleum having 50-70% SO3 to a bromodifluoroacetyl halide (bromide or chloride) and then in reacting the latter directly with either an alcohol, or with water.
