Check Digit Verification of cas no

The CAS Registry Mumber 1176043-48-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,6,0,4 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1176043-48:
(9*1)+(8*1)+(7*7)+(6*6)+(5*0)+(4*4)+(3*3)+(2*4)+(1*8)=143
143 % 10 = 3
So 1176043-48-3 is a valid CAS Registry Number.

(PhTe)2-mediated intramolecular radical cyclization of o-ethynylaryl isocyanides leading to bistellurated quinolines upon visible-light irradiation

Mitamura, Takenori,Iwata, Kimiyo,Ogawa, Akiya

, p. 3422 - 3424 (2009)

Upon treatment with (PhTe)2 under visible-light irradiation, o- ethynylaryl isocyanides underwent intramolecular radical cyclization with introduction of telluro groups, affording the corresponding bistellurated quinolines.

Photochemical intramolecular cyclization of o-alkynylaryl isocyanides with organic dichalcogenides leading to 2,4-bischalcogenated quinolines

Mitamura, Takenori,Iwata, Kimiyo,Nomoto, Akihiro,Ogawa, Akiya

experimental part, p. 3768 - 3775 (2011/06/19)

When a mixture of o-alkynylaryl isocyanides and organic dichalcogenides such as diselenides or ditellurides was irradiated with light of wavelength over 300 or 400 nm, the intramolecular cyclization of the isocyanides took place to afford the correspondin
