Check Digit Verification of cas no

The CAS Registry Mumber 205308-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,3,0 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 205308-05:
(8*2)+(7*0)+(6*5)+(5*3)+(4*0)+(3*8)+(2*0)+(1*5)=90
90 % 10 = 0
So 205308-05-0 is a valid CAS Registry Number.

Synthesis of 4-Aryl-3-(2-chromonyl)-2-pyrazolines by the 1,3-Dipolar Cycloaddition of 2-Styrylchromones with Diazomethane

Pinto, Diana C.G.A.,Silva, Artur M.S.,Almeida, Lucia M.P.M.,Cavaleiro, Jose A.S.,Levai, Albert,Patonay, Tamas

, p. 217 - 224 (1998)

The first reported 1,3-dipolar cycloaddition of 2-styrylchromones with diazomethane afforded 4-aryl-3-(2-chromonyl)-2-pyrazolines. However, 3-aryl-4-(2-chromonyl)-1-pyrazolines have been also found as minor products of this reaction. These two series of p

1,5-Diphenylpenta-2,4-dien-1-ones as potent and selective monoamine oxidase-B inhibitors

Desideri, Nicoletta,Fioravanti, Rossella,Proietti Monaco, Luca,Biava, Mariangela,Yanez, Matilde,Ortuso, Francesco,Alcaro, Stefano

, p. 91 - 100 (2013/03/13)

A series of (2E,4E)-1-(2-hydroxyphenyl)-5-phenylpenta-2,4-dien-1-ones (3a-r) and (2Z,4E)-3-hydroxy-1-(2-hydroxyphenyl)-5-phenylpenta-2,4-dien-1-ones (6a-l) were synthesized and evaluated in vitro as inhibitors of the two human Monoamine oxidase (hMAO) iso

Efficient syntheses of new polyhydroxylated 2,3-diaryl-9H-xanthen-9-ones

Santos, Clementina M. M.,Silva, Artur M. S.,Cavaleiro, Jose A. S.

experimental part, p. 2642 - 2660 (2009/10/23)

A large number of hydroxylated 2,3-diaryl-9/i-xanthen-9ones have been synthesised by two different approaches, starting either from 3-brom.o-2-m.elhyl-4H-ch:rom.en-4-one or from. (E)-3-brom.o-2-styryl-4H-chrom. en-4-ones. The former method involves Heck r

A novel and efficient route for the synthesis of hydroxylated 2,3-diarylxanthones

Santos, Clementina M. M.,Silva, Artur M. S.,Cavaleiro, José A. S.

, p. 3113 - 3116 (2008/09/19)

A novel, efficient and general route for the synthesis of hydroxylated 2,3-diarylxanthones is described. 3-Bromo-2-styryl-chromone, the key intermediate of this synthesis, is obtained by a Baker-Venkataraman rearrangement of the appropriate 2′-cinnamoylox
