57137-98-1 Usage
General Description
Pentabromoiodo benzene is a chemical compound composed of benzene, a ring of six carbon atoms with alternating single and double bonds, and pentabromoiodo, a combination of five bromine and one iodine atoms. Benzene, pentabromoiodo- is used as a reagent in the synthesis of various organic compounds, particularly in the field of organic chemistry. It exhibits high reactivity due to the presence of multiple halogen atoms attached to the benzene ring, making it useful in a variety of chemical reactions. However, it is also important to handle this compound with caution, as both benzene and halogenated compounds can be toxic and pose health risks if not used properly.
Check Digit Verification of cas no
The CAS Registry Mumber 57137-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,3 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 57137-98:
(7*5)+(6*7)+(5*1)+(4*3)+(3*7)+(2*9)+(1*8)=141
141 % 10 = 1
So 57137-98-1 is a valid CAS Registry Number.

Cross coupling of polybromoiodobenzenes with some terminal alkynes
Shishkin,Tarasova,Khlevin
experimental part, p. 1323 - 1326 (2009/07/17)
Sonogashira reactions of pentabromoiodobenzene and tetrabromo-1,4- diiodobenzene with various terminal alkynes at 20°C in benzene resulted in selective replacement of the iodine atoms with formation of the corresponding alk-1-yn-1-yl-substituted polybromobenzenes.
