2397-26-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2397-26-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2397-26:
(6*2)+(5*3)+(4*9)+(3*7)+(2*2)+(1*6)=94
94 % 10 = 4
So 2397-26-4 is a valid CAS Registry Number.

Investigations in 2,3′-biquinoline series 24. Synthesis of 3-hetarylquinolines and their 1,4-dihydro derivatives under conditions of the Vilsmeier reaction

Glushenko,Goncharov,Aksenov

, p. 973 - 978 (2008)

Methods have been developed for the synthesis of 2,3′-biquinolines, their 1′,4′-dihydro derivatives, 3-pyrid-2-ylquinolines, and 3-pyrazin-2-ylquinoline based on the interaction of hetarylethylenes and vinyl butyl ether with imidoyl chlorides and Vilsmeie

A One-Pot Synthesis of Highly Functionalized Purines

Zelli, Renaud,Zeinyeh, Wa?l,Haudecoeur, Romain,Alliot, Julien,Boucherle, Benjamin,Callebaut, Isabelle,Décout, Jean-Luc

supporting information, p. 6360 - 6363 (2017/12/08)

Highly substituted purines were synthesized in good to high yields through a one-pot straightforward metal-free scalable method, using the Traube synthesis adapted to Vilsmeier-type reagents. From 5-amino-4-chloropyrimidines, new 9-aryl-substituted chloropurines and intermediates for peptide nucleic acid synthesis were prepared. Variant procedures allowing a rapid synthesis of ribonucleosides and 7-benzylpurine from 5-amidino-6-aminopyrimidines are also reported to illustrate the high potential of this versatile toolbox. This route appears to be particularly interesting in the field of nucleic acids for a direct and rapid access to various new 8-alkylpurine nucleosides.

Polycyclic N-heterocyclic compounds. Part 86: Synthesis and evaluation of antiplatelet aggregation activity of 2,4-disubstituted 9-chloro-5,6-dihydropyrimido[5,4-d]benzazepine and related compounds

Okuda, Kensuke,Takarada, Shigeki,Hirota, Takashi,Sasaki, Kenji

, p. 780 - 792 (2015/05/13)

Libraries of tricyclic 2-substituted 4-alkylamino-9-chloro-5,6-dihydropyrimido[5,4-d]benzazepines and tetracyclic 12-substituted 8-chloro-1,2,5,6-tetrahydro-4H-imidazo[1',2':1,6]pyrimido[5,4-d]benzazepines were synthesized as part of our research to develop new effective antiplatelet drugs. Several alkyl and aryl groups were used as substituents at the 2-position. Evaluation of the effects of the newly synthesized compounds on collagen-induced platelet aggregation revealed several promising antiplatelet candidates with potencies superior to aspirin.
