Check Digit Verification of cas no
The CAS Registry Mumber 7057-97-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,5 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7057-97:
(6*7)+(5*0)+(4*5)+(3*7)+(2*9)+(1*7)=108
108 % 10 = 8
So 7057-97-8 is a valid CAS Registry Number.

Thermolysis of Polyazapentadienes. Part 8. The formation of Pyrroles from 1,1-Dialkyl-5-aryl-1,5-diazapentadienes
McNab, Hamish,Murray, M. Elizabeth-Ann
, p. 333 - 338 (2007/10/02)
Flash vacuum pyrolysis of the 1,5-diazapentadienes (4)-(10) gave moderate yields of pyrroles together with quinolines, formed by electrocyclic ring closure with elimination.The pyrroles were formed by hydrogen transfer from an N-alkyl group, followed by cyclisation and final aromatisation of the resulting dihydropyrrole intermediate by free-radical cleavage.The mechanism of the hydrogen transfer and cyclisation is not known with certainty, but may involve diradicals or 1,5-dipolar intermediates.
