Dibrommethyl-butyl-ether, also known as 1,2-dibromoethane or ethylene dibromide (EDB), is a brominated hydrocarbon compound with the chemical formula C2H4Br2. It is a colorless, volatile liquid with a sweet, chloroform-like odor. EDB was primarily used as a soil and post-harvest fumigant in agriculture to control pests and diseases in various crops, such as fruits, vegetables, and nuts. However, due to its potential health risks, including carcinogenicity and negative impacts on the environment, its use has been banned or restricted in many countries. EDB is known to be toxic to humans, causing symptoms such as dizziness, nausea, and vomiting, and it can also lead to long-term health issues like liver and kidney damage.
The CAS Registry Mumber 3492-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,9 and 2 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3492-45: (6*3)+(5*4)+(4*9)+(3*2)+(2*4)+(1*5)=93 93 % 10 = 3 So 3492-45-3 is a valid CAS Registry Number.
