The CAS Registry Mumber 171867-02-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,6 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 171867-02:
(8*1)+(7*7)+(6*1)+(5*8)+(4*6)+(3*7)+(2*0)+(1*2)=150
150 % 10 = 0
So 171867-02-0 is a valid CAS Registry Number.

On the Formation of N-Heterocycles by Thermolysis of Conjugated α-Azidoacrylates

Vogel, Claus,Delavier, Paul,Schnippenkoetter, Bernd

, p. 1591 - 1606 (2007/10/02)

The synthesis of various o-butadienyl-α-azidocinnamates 2 and β-cycloalkenyl-α-azidoacrylates 9 is described.The thermolysis of compounds 2 in solution yields the new 8,9-benzo-6-azabicyclonona-3,6,8-trienes 3 as major products, while that of 9 yields the cycloalkano-2H-pyrroles 10, which can rearrange to the cycloalkano-1H-pyrroles 11 at higher temperatures.A β-(o-vinyl)phenanthryl-α-azidoacrylate 12 was found to react on thermolysis both as a β-cycloalkenyl-α-azidoacrylate and a o-vinyl-α-azidocinnamate. - Keywords: α-Azidoacrylates, thermolysis of / α-Azidocinnamates, thermolysis of / 1H-Pyrroles / 2H-Pyrroles
