533888-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 533888-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,3,8,8 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 533888-83:
(8*5)+(7*3)+(6*3)+(5*8)+(4*8)+(3*8)+(2*8)+(1*3)=194
194 % 10 = 4
So 533888-83-4 is a valid CAS Registry Number.

Mild, rapid, and inexpensive microwave-assisted synthesis of allylic and propargylic esters

Gill, Monica A.,Manthorpe, Jeffrey M.

, p. 1460 - 1468 (2013/05/09)

A variety of allylic and propargylic esters were rapidly prepared via microwave heating of their corresponding mixed anhydride derived from pivaloyl chloride. The reaction conditions were modified to account for the sterics of the alcohol and the electronics of the carboxylic acid. Supplemental materials are available for this article.

π-Deficient α-arylsulfonyl esters as soft nucleophiles in organic synthesis

Alonso, Diego A.,Nájera, Carmen,Varea, Montserrat

, p. 8845 - 8848 (2007/10/03)

Different π-deficient arylsulfonyl groups have been studied as candidates for the stabilization of α-sulfonyl esters. The 3,5-bis(trifluoromethyl)phenylsulfonyl group has been shown to be the best substituent for the stereoselective synthesis of E-aconitates by a dialkylation-dehydrosulfinylation integrated process under PTC conditions using K2CO3 as base.
