118249-11-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118249-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,2,4 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118249-11:
(8*1)+(7*1)+(6*8)+(5*2)+(4*4)+(3*9)+(2*1)+(1*1)=119
119 % 10 = 9
So 118249-11-9 is a valid CAS Registry Number.

High-affinity disaccharide binding by tricyclic synthetic lectins

Sookcharoenpinyo, Bunyarithi,Klein, Emmanuel,Ferrand, Yann,Walker, D. Barney,Brotherhood, Peter R.,Ke, Chenfeng,Crump, Matthew P.,Davis, Anthony P.

supporting information; experimental part, p. 4586 - 4590 (2012/06/30)

Stay flexible: Rigid preorganization is not always the best approach to molecular recognition. Unlike previous synthetic lectins, new receptors (see picture) were synthesized that possess conformational freedom which allows hydrophobically driven collapse

Phenol-containing macrocyclic diamides as new catalysts in the highly regioselective conversion of epoxides to β-hydroxy thiocyanates

Sharghi,Nasseri,Niknam

, p. 7287 - 7293 (2007/10/03)

The regioselective ring-opening reactions of some epoxides with ammonium thiocyanate in the presence of a series of new phenol-containing macrocyclic diamides and also dibenzo-18-crown-6-, 18-crown-6-, benzo-15-crown-5-, and pyridine-containing macrocyclic diamide have been studied. The epoxides were subject to cleavage by NH4SCN in the presence of these catalysts under mild reaction conditions in various aprotic solvents. In this study, reagents and conditions have been discovered with which the individual β-hydroxy thiocyanates can be synthesized in high yield and with more than 90% regioselectivity. The results can be discussed in terms of a four-step mechanism: (1) formation of complex between catalyst and NH4SCN, (2) release of SCN- nucleophile from the complex, (3) reaction of the active nucleophile at the less sterically hindered site in the epoxide, and (4) regeneration of catalyst. The major advantages of this method are as follows: (1) high regioselectivity, (2) simple regeneration of catalyst, (3) its reuse through several cycles without a decrease in activity, and (4) ease of workup of the reaction.
