Check Digit Verification of cas no

The CAS Registry Mumber 252-47-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 252-47:
(5*2)+(4*5)+(3*2)+(2*4)+(1*7)=51
51 % 10 = 1
So 252-47-1 is a valid CAS Registry Number.

Flow-Vacuum Pyrolysis of Polycyclic Compounds, 6. Pyrolysis of Dibenzo 8 Hydrocarbons

Banciu, Mircea D.,Stanescu, Michaela D.,Petride, Aurica,Parvulescu, Luminitza,Pop, Mircea

, p. 2513 - 2518 (2007/10/02)

The flow-vacuum pyrolysis of dibenzo 8 hydrocarbons 2, 3, 4, and 5 are studied at 1 Torr and in the temperature range between 400 and 650 deg C.The following new transformations have been observed: 24, 2-->5, 3-->5, 34, 3-->2, 5-->11, the last three presenting analogies in the 8 and/or benzo 8 series.A reaction mechanism is suggested. - Key Words: Dibenzo 8 hydrocarbons / Flow-vacuum pyrolysis
