Check Digit Verification of cas no

The CAS Registry Mumber 541502-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,1,5,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 541502-98:
(8*5)+(7*4)+(6*1)+(5*5)+(4*0)+(3*2)+(2*9)+(1*8)=131
131 % 10 = 1
So 541502-98-1 is a valid CAS Registry Number.

A PROCESS FOR PREPARING A CRYSTALLINE FORM OF HALOBETASOL PROPIONATE

-

Page/Page column 25, (2008/06/13)

The present invention provides a process for preparing a crystalline form of halobetasol propionate, comprising the step of crystallizing halobetasol propionate from absolute ethanol or a mixture of ethanol and water, wherein the crystalline form of halobetasol propionate is characterized by an x-ray powder diffraction pattern having peaks at 10.0, 11.6, 12.9, 13.4, 14.5, 16.4, 17.6, and 23.5 + 0.2 degrees 2θ.
