34058-39-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34058-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,5 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 34058-39:
(7*3)+(6*4)+(5*0)+(4*5)+(3*8)+(2*3)+(1*9)=104
104 % 10 = 4
So 34058-39-4 is a valid CAS Registry Number.

Dehydrogenation of 3-unsubstituted indolizines on platinum on carbon. A facile synthesis of biindolizines

Sonnenschein, Helmut,Kosslick, Hendrik,Tittelbach, Franz

, p. 1596 - 1598 (1998)

Biindolizines were synthesised by oxidative dimerisation on platinum on carbon without byproducts in almost quantitative yields.

RADICAL CATIONS. PART 2. OXIDATIVE DIMERIZATION OF INDOLIZINES: A CHEMICAL AND ELECTROCHEMICAL INVESTIGATION

Andruzzi, Romano,Cardellini, Liberato,Greci, Lucedio,Stipa, Pierluigi,Poloni, Marino,Trazza, Antonio

, p. 3067 - 3070 (2007/10/02)

3-Unsubstituted indolizines undergo oxidative dimerization in the presence of catalytic amounts of Fe(III) and oxygen.Although much experimental evidence apparently indicates that Fe(II) is reoxidised to Fe(III) by oxygen, a chain mechanism cannot be envi
