344453-41-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 344453-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,4,5 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 344453-41:
(8*3)+(7*4)+(6*4)+(5*4)+(4*5)+(3*3)+(2*4)+(1*1)=134
134 % 10 = 4
So 344453-41-4 is a valid CAS Registry Number.

Routes to some 3,6-disubstituted phthalonitriles and examples of phthalocyanines derived therefrom. An overview

Heeney, Martin J.,Al-Raqa, Shaya A.,Auger, Aurélien,Burnham, Paul M.,Cammidge, Andrew N.,Chambrier, Isabelle,Cook, Michael J.

, p. 649 - 664 (2013/09/24)

The paper reviews a selection of synthetic pathways that provide access to 3,6-disubstituted phthalonitriles, precursors for the synthesis of 1,4,8,11,15,18,22,25-octasubstituted phthalocyanine derivatives. Early routes using Diels-Alder reactions for the

Synthesis and electrochemical characterisation of new tantalum (V) alkythio phthalocyanines

Chauke, Vongani,Nyokong, Tebello

experimental part, p. 3662 - 3669 (2011/02/16)

The synthesis and electrochemical characterisation of octa-pentylthio (4a) and octa-octylthio (4b) - phthalocyaninato tantalum (III) hydroxide are hereby reported. These TaPc complexes absorb in the near infrared region (~800 nm in dichloromethane). They
