Phenyl-phosphonochloridous acid phenyl ester, also known as diphenyl phosphoryl chloride or (diphenylphosphoryl)benzene, is an organophosphorus compound with the chemical formula C12H10ClO2P. It is a colorless to pale yellow liquid that is sensitive to moisture and air, and it has a pungent odor. phenyl-phosphonochloridous acid phenyl ester is primarily used as a reagent in organic synthesis, particularly in the preparation of various phosphorus-containing compounds and as a chlorinating agent. Due to its reactivity, it is important to handle it with care, typically under an inert atmosphere and using appropriate protective equipment.

2171-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2171-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.Calculate Digit Verification of CAS Registry Number 2171-93:
(6*2)+(5*1)+(4*7)+(3*1)+(2*9)+(1*3)=69
69 % 10 = 9
So 2171-93-9 is a valid CAS Registry Number.
