Check Digit Verification of cas no

The CAS Registry Mumber 109953-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,5 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109953-91:
(8*1)+(7*0)+(6*9)+(5*9)+(4*5)+(3*3)+(2*9)+(1*1)=155
155 % 10 = 5
So 109953-91-5 is a valid CAS Registry Number.

NOVEL HIGH AFFINITY QUINOLINE-BASED KINASE LIGANDS

-

Paragraph 0237, (2014/01/09)

Quinoline-based inhibitors of cyclin dependent kinase 2, compositions including the inhibitors, and methods of using the inhibitors and inhibitor compositions are described. The inhibitors and compositions including them are useful for treating disease or disease symptoms. The invention also provides for methods of making CDK-2 inhibitor compounds, methods of inhibiting CDK-2, and methods for treating disease or disease symptoms.

Synthesis of novel N-protected β3-amino nitriles: study of their hydrolysis involving a nitrilase-catalyzed step

Veitia, Maite Sylla-Iyarreta,Brun, Pierre Louis,Jorda, Pierre,Falguieres, Annie,Ferroud, Clotilde

experimental part, p. 2077 - 2089 (2010/03/04)

Several commercially available nitrilases were investigated with regard to their potential to hydrolyze N-protected β3-amino nitriles into their corresponding N-protected β3-amino acids. The biotransformations were obtained in different proportions depending on the nitrilase involved. The best hydrolysis results were achieved for the N-Cbz-β3-amino nitrile from l-alanine using the NIT-107, in a phosphate buffer at 0.05 M. However, no biotransformation into the corresponding acids was observed for the N-sulfonylamide β3-amino nitriles. Two simple and efficient procedures to prepare the β3-amino nitriles from their analogous α-amino acids are described. Thirty four new substances were synthesized and characterized over the course of this work.

Syntheses of amino alcohols and chiral C2-symmetric bisoxazolines derived from O-alkylated R-4-hydroxyphenylglycine and S-tyrosine

Caplar, Vesna,Raza, Zlata,Katalenic, Darinka,Zinic, Mladen

, p. 23 - 36 (2007/10/03)

Chiral C2-symmetric bisoxazolines 1b-f and 2b,c, derived from 4′-O-alkylated R-4-hydroxyphenylglycine or S-tyrosine, were prepared. As intermediates, a series of chiral amino alcohols possessing substituted phenolic groups was prepared and fully characterized.
