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.

NOVEL DRUG DELIVERY CONJUGATED MOIETY FOR ORAL ADMINISTRATION OF DRUG UNSUITABLE FOR ORAL ADMINISTRATION AND PREPARATION METHOD THEREOF

-

Paragraph 70; 71; 72; 73, (2017/02/09)

The present invention provides a novel drug delivery conjugated moiety for oral administration of a drug that is not suitable for oral administration or a pharmaceutically acceptable salt thereof. When the drug delivery conjugated moiety of the present invention or a pharmaceutically acceptable salt thereof is combined with a drug, which is not suitable for oral administration, and is administered orally, it exhibits an excellent absorption rate without decreasing the biological activities of the drug. Moreover, the drug delivery conjugated moiety of the present invention or a pharmaceutically acceptable salt thereof can be easily prepared in a few steps, which is very advantageous in terms of mass production.
