Check Digit Verification of cas no
The CAS Registry Mumber 1094322-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,4,3,2 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1094322-91:
(9*1)+(8*0)+(7*9)+(6*4)+(5*3)+(4*2)+(3*2)+(2*9)+(1*1)=144
144 % 10 = 4
So 1094322-91-4 is a valid CAS Registry Number.

METHOD FOR THE PURIFICATION OF MYCOPHENOLATE MOFETIL
-
Page/Page column 7, (2009/03/07)
The present invention provides a method for the preparation of mycophenolate mofetil wherein mycophenolic acid or an amine salt of mycophenolic acid is esterified with 2-morpholinoethanol, the resulting mixture is extracted into water at a pH-value between 1.0 and 3.0, and mycophenolate mofetil is back-extracted in a water-immiscible solvent at a pH-value between 3.0 and 5.0.
