General Description
1,2-Dibromo-4-iodobenzene is a chemical compound with a molecular formula of C6H3Br2I. It is an aromatic halide that belongs to the class of organobromides. This chemical appears as a red crystalline solid and it's less soluble in water, but more soluble in organic solvents such as ethanol. The chemical is often used as an intermediate for the synthesis of other compounds in various chemical reactions, including organic synthesis. It's important to note that like many chemicals, handling should be done with caution, as it may be harmful if ingested or inhaled, and can cause irritation to skin and eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 909072-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,0,7 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 909072-74:
(8*9)+(7*0)+(6*9)+(5*0)+(4*7)+(3*2)+(2*7)+(1*4)=178
178 % 10 = 8
So 909072-74-8 is a valid CAS Registry Number.

Efficient and complementary methods offering access to synthetically valuable 1,2-dibromobenzenes
Diemer, Vincent,Leroux, Frederic R.,Colobert, Fracoise

1,2-Dibromobenzenes are highly valuable precursors for various organic transformations, in particular, reactions based on the intermediate formation of benzynes. This report describes short sequences for the synthesis of various derivatives based on regioselective bromination, ortho-metalation, and halogen/metal permutations. 1,2-Dibromo-3-iodobenzene (2f), 1,2-dibromo-4- iodobenzene (4c), and 2,3-dibromo-1,4-diiodobenzene (5e) act as intermediates in these syntheses. Bromo-iodoarenes have been synthesized by short and regioselective bromination or iodination sequences that combine ortho-metalation, halo-desilylation, diazotation, or bromination reactions of anilines. These polyhalo derivatives were then used as key intermediates to access a wide range of functionalized 1,2-dibromobenzenes by chemoselective organometallic reactions. Copyright
