77831-48-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77831-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,3 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77831-48:
(7*7)+(6*7)+(5*8)+(4*3)+(3*1)+(2*4)+(1*8)=162
162 % 10 = 2
So 77831-48-2 is a valid CAS Registry Number.

Rapid synthesis and lipase inhibition activity of some new benzimidazole and perimidine derivatives

Mente?e,Y?lmaz,Karaali,ülker,Kahveci

, p. 336 - 342 (2014/06/09)

This study presents a synthesis of new series of some benzimidazole, bisbenzimidazole and perimidine derivatives via microwave technique, which, leads to the good product yields and short reaction times. The structure of newly synthesized compounds was confirmed by 1H NMR and 13C NMR spectra. These compounds were screened for their lipase inhibition activity. Then, all compounds were evaluated with regard to pancreatic lipase activity, and some of the 2-substituted perimidines, bisperimidine and bisbenzimidazole derivatives showed lipase inhibition at various concentrations.

The Synthesis of 3- and 5-Amino-1,2,4-Oxadiazoles. A Caveat

Dimsdale, Michael J.

, p. 37 - 41 (2007/10/02)

Evidence obtained from a single series of compounds demonstrates the need for care when assigning structures to amino-1,2,4-oxadiazoles using the methodology described in the literature.Certain synthetic methods can give rise to different position isomers
