66536-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66536-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,3 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66536-82:
(7*6)+(6*6)+(5*5)+(4*3)+(3*6)+(2*8)+(1*2)=151
151 % 10 = 1
So 66536-82-1 is a valid CAS Registry Number.

HIPPURISTANOLS, CYTOTOXIC POLYOXYGENATED STEROIDS FROM THE GORGONIAN ISIS HIPPURIS

Four new polyoxygenated steroids (4-7) containing a spiroketal function have been isolated from the gorgonian Isis hippuris.Their structures were determined by spectral correlation and by interconversion.Previously assigned configuration at the C-22 of hippurin-1 (3) was reversed by spectroscopic evidence.Two (4,7) of the steroids exhibited potent in vitro anticancer activities.
