Check Digit Verification of cas no

The CAS Registry Mumber 1420342-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,3,4 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1420342-23:
(9*1)+(8*4)+(7*2)+(6*0)+(5*3)+(4*4)+(3*2)+(2*2)+(1*3)=99
99 % 10 = 9
So 1420342-23-9 is a valid CAS Registry Number.

One-pot multicomponent reactions for the efficient synthesis of highly functionalized dihydropyridines

Pal, Suman,Choudhury, Lokman H.,Parvin, Tasneem

, p. 986 - 992 (2013)

An efficient, atom-economic, one-pot protocol has been developed for the synthesis of highly functionalized dihydropyridines via four-component reactions of aromatic aldehydes, arylamines, malononitrile, and dimethylacetylenedicarboxylate in the presence

Fe3O4@SiO2-NH2 nanocomposite as a robust and effective catalyst for the one-pot synthesis of polysubstituted dihydropyridines

Ghasemzadeh, Mohammad Ali,Abdollahi-Basir, Mohammad Hossein

, p. 627 - 637 (2016/10/12)

A practical, simple and efficient method for the synthesis of polysubstituted dihydropyridines was described via multicomponent reactions of aldehydes, arylamines, dimethyl acetylenedicarboxylate and malononitrile/ethyl acetoacetate in the presence of Fe3O4@SiO2-NH2 nanocomposites. The present methodology provides a novel and efficient method for the synthesis of dihydropyridine derivatives with some advantages, such as excellent yields, short reaction times, recoverability and low catalyst loading. The nanomagnetic catalyst could be readily recovered using an external magnet and reused several times without any significant loss in activity. The catalyst was fully characterized by FT-IR, SEM, XRD, EDX and VSM analysis.

KF/Al2O3 mediated multicomponent reactions for the efficient synthesis of highly substituted dihydropyridines

Pal, Suman,Khan, Md. Nasim,Choudhury, Lokman H.

, p. E156-E162 (2014/11/07)

KF/Al2O3 was found to be an efficient solid supported catalyst for the facile access of highly substituted dihydropyridine derivatives from the multicomponent reaction of aromatic aldehydes, amines, malononitrile, and alkylacetylened
