Check Digit Verification of cas no

The CAS Registry Mumber 33304-34-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33304-34:
(7*3)+(6*3)+(5*3)+(4*0)+(3*4)+(2*3)+(1*4)=76
76 % 10 = 6
So 33304-34-6 is a valid CAS Registry Number.

Pyrolytic cyclisation reactions of 3-azolylpropenyl alcohols; unexpectedly facile thermal decomposition of 5H-pyrrolo-[2,1-a]isoindole

Clark, Bernard A. J.,Despinoy, Xavier L. M.,McNab, Hamish,Sommerville, Craig C.,Stevenson, Elizabeth

, p. 2049 - 2051 (2007/10/03)

Flash vacuum pyrolysis (FVP) of 3-azolylpropenyl alcohols 5-7, 12 or 15 at 650-700°C (10-2-10-3 Torr) causes loss of water and cyclisation to give 3H-pyrrolizine 8 and its analogues 9, 10, 13 and 16; at higher temperatures (e.g. 900°C) 5H-pyrrolo[2,1-a]isoindole 13 decomposes by loss of HCN to give naphthalene 18 and benzofulvene 19 and the mechanism of this transformation is studied by deuterium labelling.
