189818-30-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189818-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,1 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189818-30:
(8*1)+(7*8)+(6*9)+(5*8)+(4*1)+(3*8)+(2*3)+(1*0)=192
192 % 10 = 2
So 189818-30-2 is a valid CAS Registry Number.

Design, synthesis, and evaluation of tetrahydropyrimidinones as an example of a general approach to nonpeptide HIV protease inhibitors

De Lucca, George V.,Liang, Jing,Aldrich, Paul E.,Calabrese, Joe,Cordova, Beverly,Klabe, Ronald M.,Rayner, Marlene M.,Chang, Chong-Hwan

, p. 1707 - 1719 (2007/10/03)

Re-examination of the design of the cyclic urea class of HIV protease (HIVPR) inhibitors suggests a general approach to designing novel nonpeptide cyclic HIVPR inhibitors. This process involves the inversion of the stereochemical centers of the core transition-state isostere of the linear HIVPR inhibitors and cyclization of the resulting core using an appropriate cyclizing reagent. As an example, this process is applied to the diamino alcohol class of HIVPR inhibitors to give tetrahydropyrimidinones. Conformational analysis of the tetrahydropyrimidinones and modeling of its interaction with the active site of HIVPR suggested modifications which led to very potent inhibitors of HIVPR (24 with a K(i) = 0.018 nM). The X-ray crystallographic structure of the complex of 24 with HIVPR confirms the analysis and modeling predictions. The example reported in this study and other examples that are cited indicate that this process may be generally applicable to other linear inhibitors.
