Check Digit Verification of cas no

The CAS Registry Mumber 299969-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,9,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 299969-20:
(8*2)+(7*9)+(6*9)+(5*9)+(4*6)+(3*9)+(2*2)+(1*0)=233
233 % 10 = 3
So 299969-20-3 is a valid CAS Registry Number.

Preparation of 1-D nanoparticle superstructures with tailorable thicknesses using gold-binding peptide conjugates

Hwang, Leekyoung,Chen, Chun-Long,Rosi, Nathaniel L.

, p. 185 - 187 (2011)

We describe the preparation of new 1-D gold nanoparticle superstructures with tailorable thicknesses formed using a self-assembled gold-binding peptide conjugate template and examine how the synthesis and assembly mechanism impacts the organization of the

General method for the preparation of active esters by palladium-catalyzed alkoxycarbonylation of aryl bromides

De Almeida, Angelina M.,Andersen, Thomas L.,Lindhardt, Anders T.,De Almeida, Mauro V.,Skrydstrup, Troels

supporting information, p. 1920 - 1928 (2015/02/19)

A useful method was developed for the synthesis of active esters by palladium-catalyzed alkoxycarbonylation of (hetero)aromatic bromides. The protocol was general for a range of oxygen nucleophiles including N-hydroxysuccinimide (NHS), pentafluorophenol (PFP), hexafluoroisopropyl alcohol (HFP), 4-nitrophenol, and N-hydroxyphthalimide. A high functional group tolerance was displayed, and several active esters were prepared with good to excellent isolated yields. The protocol was extended to access an important synthetic precursor to the HIV-protease inhibitor, saquinavir, by formation of an NHS ester followed by acyl substitution.

In silico-aided design of a glycan ligand of sialoadhesin for in vivo targeting of macrophages

Nycholat, Corwin M.,Rademacher, Christoph,Kawasaki, Norihito,Paulson, James C.

supporting information, p. 15696 - 15699,4 (2020/08/24)

Cell-specific delivery of therapeutic agents using ligand targeting is gaining interest because of its potential for increased efficacy and reduced side effects. The challenge is to develop a suitable ligand for a cell-surface receptor that is selectively
