Dibromo-1,1-ethyliden-3-dimethyl-2,2-cyclopropan, also known as 1,1-dibromo-3,3-dimethyl-2-ethylidenecyclopropane, is a halogenated cyclopropane derivative. This organic compound features a three-carbon cyclopropane ring with two bromine atoms attached to the first carbon, an ethylidene group (a carbon-carbon double bond) between the first and second carbons, and two methyl groups attached to the third carbon. Due to its unique structure and properties, this chemical can be used in various applications, such as a precursor in the synthesis of other organic compounds or as an intermediate in chemical reactions. However, it is essential to handle Dibromo-1,1-ethyliden-3-dimethyl-2,2-cyclopropan with care, as halogenated hydrocarbons can pose health and environmental risks.
The CAS Registry Mumber 5239-76-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5239-76: (6*5)+(5*2)+(4*3)+(3*9)+(2*7)+(1*6)=99 99 % 10 = 9 So 5239-76-9 is a valid CAS Registry Number.
