25-85-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25-85-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 2 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25-85:
(4*2)+(3*5)+(2*8)+(1*5)=44
44 % 10 = 4
So 25-85-4 is a valid CAS Registry Number.

Sorption effect on kinetics of etherification of TERT-AMYL ALCOHOL (cas 25-85-4) and ethanol09/30/2019

The kinetics of the etherification of tert-amyl alcohol with ethanol, catalysed by a strong ion-exchange resin, Amberlyst 15, has been studied in a batch reactor at temperatures between 323 and 353K and at a pressure of 0.8MPa. The kinetics was described by a coupled sorption-reaction model. Flo...detailed
