950-28-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 950-28-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 950-28:
(5*9)+(4*5)+(3*0)+(2*2)+(1*8)=77
77 % 10 = 7
So 950-28-7 is a valid CAS Registry Number.

α-methylenation/Diels-Alder tandem reaction promoted by ammonium salts generatedin situ from secondary-tertiary diamines and alkoxymethyl chlorides

Nakamura, Hiroko,Yamamoto, Hisashi

, p. 1648 - 1649 (2007/10/03)

A simple one-pot synthesis of spiranones from cycloketones and dienes promoted by an ammonium salt generatedin situ from diamine and alkoxymethyl chloride through a tandem α-methylenation/Diels-Alder reaction is described.

New directions in the condensation reactions of cyclohexanone and its Mannich base

Fedotova,Kapitonova,Reshetov,Tsimbalenko

, p. 773 - 777 (2007/10/03)

An unusual direction was found in the condensation of cyclohexanone and its Mannich base, leading to the formation of previously unknown polycydic spirohydrochromans. The structure of the compounds was confirmed by 13C NMR and mass spectrometry. 1998 Plenum Publishing Corporation.

Properties and antiphage activity of condensed hydro(thio)chromans and their copper complexes

Fedotova,Lipatova,Kapitonova,Reshetov,Plotnikov,Kharchenko

, p. 1131 - 1135 (2007/10/03)

Research into the reactivity of carbonyl-substituted spirohydrochromans with hydrogen sulfide under the influence of protic and aprotic acids was continued for the case of 3,4,5,6,7,8-hexahydrospiro[chromene-2,1′-cyclohexan]-2-one. The general nature of the reactions was established. Complexes of copper(II) with substituted hydro(thio)chromans were obtained. The results from investigation of the antiphage activity of the synthesized compounds are presented. 1997 Plenum Publishing Corporation.
