Check Digit Verification of cas no

The CAS Registry Mumber 28512-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,1 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28512-33:
(7*2)+(6*8)+(5*5)+(4*1)+(3*2)+(2*3)+(1*3)=106
106 % 10 = 6
So 28512-33-6 is a valid CAS Registry Number.

A new class of organogelators based on triphenylmethyl derivatives of primary alcohols: Hydrophobic interactions alone can mediate gelation

Singh, Wangkhem P.,Singh, Rajkumar S.

supporting information, p. 138 - 149 (2017/02/15)

In the present work, we have explored the use of the triphenylmethyl group, a commonly used protecting group for primary alcohols as a gelling structural component in the design of molecular gelators. We synthesized a small library of triphenylmethyl deri

Synthesis of a library of propargylated and PEGylated α-hydroxy acids toward "clickable" polylactides via hydrolysis of cyanohydrin derivatives

Zhang, Quanxuan,Ren, Hong,Baker, Gregory L.

, p. 9546 - 9555 (2015/02/19)

A new simple and practical protocol for scalable synthesis of a novel library of propargylated and PEGylated α-hydroxy acids toward the preparation of "clickable" polylactides was described. The overall synthesis starting from readily available propargyl alcohol, bromoacetaldehyde diethyl acetal, and OEGs or PEGs was developed as a convenient procedure with low cost and no need of column chromatographic purification. The terminal alkyne functionality survives from hydrolysis of the corresponding easily accessible cyanohydrin derivatives in methanolic sulfuric acid. Facile desymmetrization, monofunctionalization, and efficient chain-elongation coupling of OEGs further enable the incorporation of OEGs to α-hydroxy acids in a simple and efficient manner. At the end, synthesis of allyloxy lactic acid indicates that an alkene group is also compatible with the developed method. (Chemical Equation Presented).

N, N′ - Ditritylurea and analogs as hosts in crystalline clathrate complexes: Synthesis and selectivity studies

Ng, Kwok-Keung Daniel,Hart, Harold

, p. 7883 - 7906 (2007/10/02)

Of 38 hosts, most of them new, designed on the 'wheel-and-axle' model, 24 formed clathrate complexes with small molecules; 95 new host/guest combinations are described (Table 6). Selectivity studies (Table 7) show, in some instances, substantial discrimin
