Pentafluorophenylaluminum di bromide is a chemical compound with the formula C6F5AlBr2. It is a derivative of aluminum, where a pentafluorophenyl group (C6F5) is bonded to an aluminum atom, and two bromide ions (Br-) are attached to the aluminum. This organoaluminum compound is known for its strong Lewis acid properties, which makes it a useful reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and the activation of various substrates. Due to its reactivity and potential hazards, it is important to handle PENTAFLUOROPHENYLALUMINUM DIBROMIDE with care, following appropriate safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 4457-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4457-90:
(6*4)+(5*4)+(4*5)+(3*7)+(2*9)+(1*0)=103
103 % 10 = 3
So 4457-90-3 is a valid CAS Registry Number.
