Check Digit Verification of cas no
The CAS Registry Mumber 865792-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,7,9 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 865792-18:
(8*8)+(7*6)+(6*5)+(5*7)+(4*9)+(3*2)+(2*1)+(1*8)=223
223 % 10 = 3
So 865792-18-3 is a valid CAS Registry Number.

-
Page/Page column 3, (2008/06/13)
The present invention provides a process for preparing high purity cilostazol. The process comprises: (a) adding crude cilostazol to an acid selected from the group consisting of oxalic acid, maleic acid, sulfuric acid, and a mixture thereof to form a cilostazol salt; and (b) recovering cilostazol through adding a base to the cilostazol salt.
