Check Digit Verification of cas no

The CAS Registry Mumber 719280-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,9,2,8 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 719280-89:
(8*7)+(7*1)+(6*9)+(5*2)+(4*8)+(3*0)+(2*8)+(1*9)=184
184 % 10 = 4
So 719280-89-4 is a valid CAS Registry Number.

Fine tuning the outcome of 1,3-dipolar cycloaddition reactions of benzimidazolium ylides to activated alkynes

Georgescu, Emilian,Nicolescu, Alina,Georgescu, Florentina,Teodorescu, Florina,Shova, Sergiu,Marinoiu, Adriana T.,Dumitrascu, Florea,Deleanu, Calin

, p. 2507 - 2520 (2016/04/26)

1,3-Dipolar cycloaddition reactions of benzimidazolium ylides, generated from 3-phenacylbenzimidazolium bromides, to non-symmetrical activated dipolarophiles in various reaction conditions led to complex mixtures of pyrrolo[1,2-a]benzimidazole and pyrrolo[1,2-a]quinoxaline derivatives. In order to explain all experimental results, the influence of reaction conditions on the reaction products was investigated. For the first time, 4-hydroxy-4,5-dihydropyrrolo[1,2-a]quinoxaline derivatives 6, pyrrolo[1,2-a]quinoxalinium quaternary salts 8, as well as 4-methoxy-4,5-dihydropyrrolo[1,2-a]quinoxalines 9, were separated, fully characterized and their interconversions are presented, together with a proposed reaction mechanism.

Unexpected formation of pyrrolo[1,2-a]quinoxaline derivatives during the multicomponent synthesis of pyrrolo[1,2-a]benzimidazoles

Nicolescu, Alina,Deleanu, Calin,Georgescu, Emilian,Georgescu, Florentina,Iurascu, Ana-Maria,Shova, Sergiu,Filip, Petru

, p. 1486 - 1488 (2013/04/23)

New pyrrolo[1,2-a]benzimidazole and pyrrolo[1,2-a]quinoxaline derivatives are obtained via one-pot, three-component reactions from 1-benzylbenzimidazoles, α-bromocarbonyl compounds, and non-symmetrical activated acetylenic dipolarophiles in propylene oxide as both the reaction medium and acid scavenger, at room temperature. When the same reaction is performed in 1,2-epoxybutane at reflux temperature only the pyrrolo[1,2-a]benzimidazole derivative is obtained. Copyright
