Check Digit Verification of cas no

The CAS Registry Mumber 13515-95-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,1 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13515-95:
(7*1)+(6*3)+(5*5)+(4*1)+(3*5)+(2*9)+(1*5)=92
92 % 10 = 2
So 13515-95-2 is a valid CAS Registry Number.

Understanding the binding properties of phosphorylated glycoluril-derived molecular tweezers and selective nanomolar binding of natural polyamines in aqueous solution

Heilmann, Michael,Knezevic, Melina,Piccini, Giovannimaria,Tiefenbacher, Konrad

supporting information, p. 3628 - 3633 (2021/05/04)

A modular synthetic platform for the construction of flexible glycoluril-derived molecular tweezers was developed. The binding properties of four exemplary supramolecular hosts obtained via this approach towards 16 organic amines were investigated by means of 1H NMR titration. In this work, we compare the Ka values obtained this way with those of three structurally related molecular tweezers and provide a computational approach towards an explanation of the observed behavior of those novel hosts. The results showcase that certain structural modifications lead to very potent and selective binders of natural polyamines, with observed binding of spermine below 10 nM. This journal is

Novel chiral derivatizing agents for 1H NMR determination of enantiomeric purities of carboxylic acids

Wada, Koji,Goto, Mizuko,Yamashita, Hiroshi,Nagasawa, Kazuo

, p. 964 - 978 (2017/06/13)

(S)-4-(3-Aminopyrrolidin-1-yl)coumarin (1), (S)-4-(3-aminopiperidin-1-yl)coumarin (4), and (S)-4-(3-aminoazepan-1-yl)coumarin (7), prepared from 4-chlorocoumarin and (S)-pyrrolidin-3-amine, (S)-piperidin-3-amine, and (S)-azepan-3-amine, respectively, were proven to be versatile and reliable 1H NMR optical purity determination agents for chiral carboxylic acids.

Supramolecular self-assembly of chiral polyimides driven by repeat units and end groups

Yan, Jijun,Kang, Chuanqing,Bian, Zheng,Jin, Rizhe,Ma, Xiaoye,Gao, Lianxun

supporting information, p. 14723 - 14729 (2017/11/28)

Pyromellitic diimides (PMDIs) are effective building blocks for the construction of supramolecular systems but are infrequently used in comparison with other electron-deficient aromatic systems. We report PMDI-based chiral polyimides that form polymeric supramolecular systems with unique self-assembly features that show time-dependent spectroscopic behaviour. Extensive investigations revealed the driving forces for the self-assembly of the polyimides. One is the complementary aromatic π-π stacking between electron-accepting PMDI and electron-donating phenyl ring in the polymer backbones, and another is the hydrogen bonding interactions of the end groups. The self-assembly is readily disrupted by guest molecules with strong associations with the PMDI and the end groups. The introduction of flexible arylether diimides into the PMDI-based copolymer backbones and the sequence of PMDIs and arylether diimides in the copolymer backbones significantly influence the self-assembly of the polyimides. The results elucidate the mechanisms of polymeric self-assembly of chiral polyimides, providing important information for the development of materials based on polymeric supramolecular systems with properties and functions regulated by composition, sequence and end groups.
