91687-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91687-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,8 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91687-44:
(7*9)+(6*1)+(5*6)+(4*8)+(3*7)+(2*4)+(1*4)=164
164 % 10 = 4
So 91687-44-4 is a valid CAS Registry Number.

From glycerol to chlorohydrin esters using a solvent-free system. Microwave irradiation versus conventional heating

Escribà, Marc,Eras, Jordi,Duran, Miquel,Simon, Sílvia,Butchosa, Cristina,Villorbina, Gemma,Balcells, Mercè,Canela, Ramon

experimental part, p. 10370 - 10376 (2010/02/27)

Esterification-chlorination of glycerol provides chlorohydrin esters in high yields. A ratio of reagents close to equivalence can be used, so that atom economy of the reaction is optimized. The reaction can be carried out using either classical or microwa

Combining AlCl3·6H2O and an ionic liquid to prepare chlorohydrin esters from glycerol

Villorbina, Gemma,Tomàs, Albert,Escribà, Marc,Oromí-Farrús, Mireia,Eras, Jordi,Balcells, Mercè,Canela, Ramon

experimental part, p. 2828 - 2830 (2009/09/30)

We describe here the first example in which glycerol has been transformed into chlorohydrin esters using an ionic liquid and hydrated aluminium chloride. The method avoids using Crown-18 ether, which was needed to obtain a similar yield when KCl was used.
