Check Digit Verification of cas no
The CAS Registry Mumber 6486-93-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6486-93:
(6*6)+(5*4)+(4*8)+(3*6)+(2*9)+(1*3)=127
127 % 10 = 7
So 6486-93-7 is a valid CAS Registry Number.

Novel anthraquinones and process for the preparation and method of use thereof
-
Page/Page column 3; 5; figure 2, (2008/06/13)
A process for the preparation of hydroxyl substituted anthraquinones is described. The process couples a phthalic anhydride (substituted or unsubstituted) to benzene ring moiety substituted with at least two hydroxyl groups. Remaining hydroxy groups were converted to methoxy groups in some anthraquinones. The compounds are particularly useful for the treatment of parasitic diseases. Also, a method of treating or preventing malaria, filariasis schistosomiasis and other parasitic diseases using anthraquinones.
