Check Digit Verification of cas no

The CAS Registry Mumber 103653-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,5 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103653-14:
(8*1)+(7*0)+(6*3)+(5*6)+(4*5)+(3*3)+(2*1)+(1*4)=91
91 % 10 = 1
So 103653-14-1 is a valid CAS Registry Number.

The metalation of chloro- and methoxy-substituted acetophenone ketals with butyllithium (BuLi) and with N,N,N',N″,N″-pentamethyldiethylenetriamine-complexed butyllithium (BuLi/PMDTA) has been investigated. The lithio species thus generated were carboxylat

Discovery of a long-acting, peripherally selective inhibitor of catechol- O -methyltransferase

experimental part, p. 3396 - 3411 (2010/09/05)

Novel nitrocatechol-substituted heterocycles were designed and evaluated for their ability to inhibit catechol-O-methyltransferase (COMT). Replacement of the pyrazole core of the initial hit 4 with a 1,2,4-oxadiazole ring resulted in a series of compounds endowed with longer duration of COMT inhibition. Incorporation of a pyridine N-oxide residue at position 3 of the 1,2,4-oxadiazole ring led to analogue 37f, which was found to possess activity comparable to entacapone and lower toxicity in comparison to tolcapone. Lead structure 37f was systematically modified in order to improve selectivity and duration of COMT inhibition as well as to minimize toxicity. Oxadiazole 37d (2,5-dichloro-3-(5-(3,4-dihydroxy-5-nitrophenyl)-1,2,4-oxadiazol-3-yl)-4, 6-dimethylpyridine 1-oxide (BIA 9-1067)) was identified as a long-acting, purely peripheral inhibitor, which is currently under clinical evaluation as an adjunct to l-Dopa therapy of Parkinson's disease.
