Check Digit Verification of cas no

The CAS Registry Mumber 144163-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,6 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144163-88:
(8*1)+(7*4)+(6*4)+(5*1)+(4*6)+(3*3)+(2*8)+(1*8)=122
122 % 10 = 2
So 144163-88-2 is a valid CAS Registry Number.

Directed reductive amination of β-hydroxy-ketones: Convergent assembly of the ritonavir/lopinavir core

Menche, Dirk,Arikan, Fatih,Li, Jun,Rudolph, Sven

, p. 267 - 270 (2007/10/03)

(Chemical Equation Presented) An efficient procedure for the directed reductive amination of β-hydroxy-ketones (3) for the stereoselective preparation of 1,3-syn-amino alcohols (6) is reported. The operationally simple protocol uses Ti(iOPr)su

Small hydroxyethylene-based peptidomimetics inhibiting both HIV-1 and C. albicans aspartic proteases

Tossi, Alessandro,Benedetti, Fabio,Norbedo, Stefano,Skrbec, Damiano,Berti, Federico,Romeo, Domenico

, p. 4719 - 4727 (2007/10/03)

We have extended a highly flexible method for rapidly assembling aspartic protease inhibitors to produce symmetric and asymmetric monohydroxyethylene peptidomimetics. This method is based on the prior synthesis of the central non-cleavable peptide-bond is

Epoxyalcohol route to hydroxyethylene dipeptide isosteres: A new synthesis of the diaminoalcohol core of HIV-protease inhibitor ABT-538 (Ritonavir)

Benedetti,Norbedo

, p. 203 - 204 (2007/10/03)

A stereoselective synthesis of the diaminoalcohol core of Ritonavir illustrates a novel approach to hydroxyethylene dipeptide isosteres, based on the regioselective reduction of amino acid-derived epoxyalcohols.
