Check Digit Verification of cas no

The CAS Registry Mumber 65513-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65513-20:
(7*6)+(6*5)+(5*5)+(4*1)+(3*3)+(2*2)+(1*0)=114
114 % 10 = 4
So 65513-20-4 is a valid CAS Registry Number.

Isomerization of linear to angular [3]phenylene and PAHs under flash vacuum pyrolysis conditions

Dosa, Peter I.,Schleifenbaum, Andreas,Vollhardt, K. Peter C.

, p. 1017 - 1020 (2007/10/03)

(matrix presented) Flash vacuum pyrolysis (FVP) of linear [3]phenylene affords its angular counterpart and the same mixture of polycyclic aromatic hydrocarbon isomers as that observed on FVP of angular [3]phenylene. A mechanism, supported by a 13C labeling study, is proposed to explain these results.
