Check Digit Verification of cas no

The CAS Registry Mumber 90580-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90580-91:
(7*9)+(6*0)+(5*5)+(4*8)+(3*0)+(2*9)+(1*1)=139
139 % 10 = 9
So 90580-91-9 is a valid CAS Registry Number.

Multistep Reversible Redox Systems, XXXIV. - Polyenes as Four-Step Redox Systems: Synthesis and Spectroscopy

Hagenbruch, Bernd,Huenig, Siegfried

, p. 340 - 353 (2007/10/02)

The synthesis of the pentaenes 2.0-4.0 and of the polyenes 2.1-2.4 is described.All alkenes carry rigid, cross-conjugated end groups.The Dienone 6, the polyene aldehydes 18 and 19 as well as the phosphorous ylid 22 serve as crucial intermediates. 1H NMR and UV/VIS spectra of all polyenes are discussed.
