Check Digit Verification of cas no

The CAS Registry Mumber 1423448-01-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,3,4,4 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1423448-01:
(9*1)+(8*4)+(7*2)+(6*3)+(5*4)+(4*4)+(3*8)+(2*0)+(1*1)=134
134 % 10 = 4
So 1423448-01-4 is a valid CAS Registry Number.

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

supporting information, 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
