General Description
Ethanesulfonic anhydride, also known as methanesulfonic anhydride, is a chemical compound with the formula (CH3SO)2O. It is a strong acylating agent and is used in the synthesis of various organic compounds. Ethanesulfonic anhydride is commonly used as a reagent in the conversion of alcohols into esters and in the acylation of amines and phenols. It is known for its ability to convert primary and secondary alcohols into their corresponding esters under mild conditions. Additionally, it can be used as a catalyst in esterification and ester cleavage reactions. Its acylating properties make it a valuable tool in organic synthesis and industrial applications.Check Digit Verification of cas no
The CAS Registry Mumber 13223-06-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,2 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.Calculate Digit Verification of CAS Registry Number 13223-06:
(7*1)+(6*3)+(5*2)+(4*2)+(3*3)+(2*0)+(1*6)=58
58 % 10 = 8
So 13223-06-8 is a valid CAS Registry Number.
