Check Digit Verification of cas no

The CAS Registry Mumber 874339-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,3,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 874339-83:
(8*8)+(7*7)+(6*4)+(5*3)+(4*3)+(3*9)+(2*8)+(1*3)=210
210 % 10 = 0
So 874339-83-0 is a valid CAS Registry Number.

LYSINE BASED COMPOUNDS

-

Page/Page column 56, (2008/06/13)

The present invention provides lysine based compounds of the formula (I); and when the compound of formula (I) comprises an amino group, pharmaceutically acceptable ammonium salts thereof, wherein Rl may be, for example, (HO)2P(O)-, (NaO)2P(O)-, alkyl-CO- or cycloalkyl-CO-, wherein X may be, for example, F, Cl, and Br, and wherein R2 and R3 are as defined herein. These lysine based compounds have a physiologically cleavable unit, namely R1 , whereby upon cleavage of the unit, an HIV aspartyl protease inhibitor is released,
