<(4-Chlor-benzoyl)-cyan-methylen>-triphenylphosphoran, also known as 4-chlorobenzoylcyanomethyl triphenylphosphorane, is a complex organic compound with the molecular formula C25H18ClNO2P. 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 4-chlorobenzoyl group in <(4-Chlor-benzoyl)-cyan-methylen>-triphenylphosphoran provides a specific electronic and steric influence on the reaction, potentially altering the reactivity and selectivity of the olefination process.

Check Digit Verification of cas no

The CAS Registry Mumber 5068-00-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,6 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5068-00:
(6*5)+(5*0)+(4*6)+(3*8)+(2*0)+(1*0)=78
78 % 10 = 8
So 5068-00-8 is a valid CAS Registry Number.
