Check Digit Verification of cas no

The CAS Registry Mumber 728887-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,8,8,8 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 728887-50:
(8*7)+(7*2)+(6*8)+(5*8)+(4*8)+(3*7)+(2*5)+(1*0)=221
221 % 10 = 1
So 728887-50-1 is a valid CAS Registry Number.

Synthesis and biological screening of novel derivatives of 3-(N-substituted carboxamidoethylthio)-(4H)-1,2,4-triazoles

Manikrao, Anil M.,Fursule, Ravindra A.,Rajesh,Kunjwani, Harish K.,Sabale, Prafulla M.

, p. 1642 - 1647 (2011/03/17)

3-Mercapto-(4H)-1,2,4-triazole has been synthesized from 1-formylthiosemicarbazide. Different N-substituted β-chloropropionamides have been prepared by reacting substituted amines with β- chloropropionylchloride. Different Nsubstituted β-chloropropionamides have been condensed with 3-mercapto-(4H)-1,2,4-triazole in basic medium to obtain various 3-(N-substituted carboxamidoethylthio)-(4H)-1,2,4-triazoles. The structure of the synthesized compounds are confirmed by IR, 1H NMR spectra and elemental analysis. All the compounds have been screened for their analgesic, anti-inflammatory and anxiolytic activity.
