Check Digit Verification of cas no

The CAS Registry Mumber 340722-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,7,2 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 340722-52:
(8*3)+(7*4)+(6*0)+(5*7)+(4*2)+(3*2)+(2*5)+(1*2)=113
113 % 10 = 3
So 340722-52-3 is a valid CAS Registry Number.

Compounds Combining a Macrocyclic Building Block and Flexible Side-Arms as Carbohydrate Receptors: Syntheses and Structure-Binding Activity Relationship Studies

Amrhein, Felix,Mazik, Monika

, p. 6282 - 6303 (2021/09/18)

A series of new representatives of compounds combining a macrocyclic building block and flexible side-arms were prepared and their ability to act as carbohydrate receptors evaluated. The target compounds were obtained by multi-step syntheses, which included the preparation of numerous precursors as well as the isolation of a large number of by-products. The structure-binding activity relationship studies comprise, in particular, the variation of the side-arms in order to demonstrate the importance of the presence of a hydrogen bond donor in these units for the effective complexation of carbohydrates. Based on the findings of our previous studies, the variation of the bridge units is limited to benzene- and pyrrole-based moieties, whereby the use of the last-mentioned bridge type was expected to produce more effective systems. This assumption was confirmed by 1H NMR titrations and isothermal titration calorimetry.

Metal triggered fluorescence sensing of citrate using a synthetic receptor

Cabell, Larry A.

, p. 315 - 323 (2007/10/03)

A metal containing fluorescent chemosensor was designed, synthesized, and studied for the quantification of citrate in common beverages. The sensor consists of Cu(II) bound by a 1,10-phenanthroline ligand which is attached to a bis(aminoimidazolium) recep
