α-Brom-α-cyano-methylen-triphenylphosphoran, also known as α-bromo-α-cyano-methylenetriphenylphosphorane, is a complex organic compound with the chemical formula C23H16BrNP. It is a phosphorus-containing reagent used in organic synthesis, particularly in the formation of carbon-carbon bonds through the Wittig reaction. This reaction involves the conversion of aldehydes or ketones into olefins by reacting with the phosphorane, which acts as a nucleophile. The α-bromo-α-cyano-methylenetriphenylphosphorane is a modified version of the standard Wittig reagent, featuring a bromine atom and a cyano group, which can influence the reactivity and selectivity of the reaction. It is a colorless to pale yellow solid, sensitive to air and moisture, and is typically used in anhydrous conditions. Due to its reactivity, it is important to handle α-Brom-α-cyano-methylen-triphenylphosphoran with care, using appropriate safety measures.

Check Digit Verification of cas no

The CAS Registry Mumber 53366-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,3,6 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 53366-72:
(7*5)+(6*3)+(5*3)+(4*6)+(3*6)+(2*7)+(1*2)=126
126 % 10 = 6
So 53366-72-6 is a valid CAS Registry Number.
