Check Digit Verification of cas no

The CAS Registry Mumber 203-12-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 203-12:
(5*2)+(4*0)+(3*3)+(2*1)+(1*2)=23
23 % 10 = 3
So 203-12-3 is a valid CAS Registry Number.

Use of external radical sources in flash vacuum pyrolysis to facilitate cyclodehydrogenation reactions in polycyclic aromatic hydrocarbons

Amick, Aaron W.,Martin, Sara E.

, p. 1338 - 1343 (2014/11/08)

A new process to facilitate the cyclodehydrogenation of polycyclic aromatic hydrocarbons (PAHs) in flash vacuum pyrolysis (FVP) using an external radical source is described. Using hexanes as an external radical source the conversion of various PAHs to their cyclodehydrogenated products is vastly increased. Various other volatile organic compounds were also examined to determine their ability to act as external radical sources in FVP.

Facile bucky-bowl synthesis by regiospecific cove-region closure by Hf elimination

supporting information; experimental part, p. 4594 - 4597 (2012/06/30)

Building bowls: An effective intramolecular aryl-aryl coupling is the key step in rational fullerene synthesis and in synthesis of extended buckybowl structures. Such a process can be embodied very efficiently through quantitative HF elimination on active Al2O3. The process is characterized by an unprecedentedly high chemoselectivity and regiospecificity.
