Check Digit Verification of cas no

The CAS Registry Mumber 173468-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,6 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 173468-90:
(8*1)+(7*7)+(6*3)+(5*4)+(4*6)+(3*8)+(2*9)+(1*0)=161
161 % 10 = 1
So 173468-90-1 is a valid CAS Registry Number.

Novel bridgehead nitrogen heterocycles: Facile synthesis and antimicrobial activity of 2,3-diaryl-3,3a,6,7,8,9-hexahydro-2H-pyrazolothiazolodiazepines

Mohan, Jag,Singh, Virender,Malik, Nirmal

, p. 1105 - 1106 (2007/10/03)

A facile synthesis of 2,3-diaryl-3,3a,6,7,8,9-hexahydro-2H-pyrazolothiazolodiazepines (3) has been achieved in a single-step by treating 2-arylidene-5,6,7,8-tetrahydrothiazolodiazepin-3(2H)-ones (2) with hydrazines.Compounds 2 is turn have been obtained in a single-step by condensing 4,5,6,7-tetrahydro-1H-1,3-diazepine-2-thiol (1) with ethyl chloroacetate and aldehydes in the presence of pyridine and piperidine.Compounds 3 represent a novel and hitherto unknown heterocyclic system.The antibacterial and antifungal activities of some of the compounds of this system have also been evaluated.
