100876-90-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100876-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,7 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100876-90:
(8*1)+(7*0)+(6*0)+(5*8)+(4*7)+(3*6)+(2*9)+(1*0)=112
112 % 10 = 2
So 100876-90-2 is a valid CAS Registry Number.

One-pot formation of aromatic tetraurea macrocycles

Wu, Zehui,Hu, Ting,He, Lan,Gong, Bing

, p. 2504 - 2507 (2012/07/13)

Treating derivatives of m-phenylenediamine having different electron-richness and reactivities with triphosgene in the presence of triethylamine led to aromatic tetraurea macrocycles in high yields. Factors important for efficiently forming these macrocycles include the molar ratio (2:1) between the diamine and triphosgene, reaction temperature (-75 °C), and solvent (CH2Cl2). By controlling the order and rate for adding diamines, tetraurea macrocycles consisting of two different types of monomeric residues have also been obtained in high yields.

Cylindrical sheet formation of oligo-meta-aniline foldamers

Maurizot, Victor,Massip, Stephane,Leger, Jean-Michel,Deleris, Gerard

supporting information; experimental part, p. 5698 - 5700 (2010/01/31)

Ortho-nitro- and ortho-alkoxy-oligo-meta-aniline units fold in solution through hydrogen bonds and aromatic stacking into compact structures that were characterized in the solid state as cylindrical β-sheet like structures.
