84202-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84202-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84202-19:
(7*8)+(6*4)+(5*2)+(4*0)+(3*2)+(2*1)+(1*9)=107
107 % 10 = 7
So 84202-19-7 is a valid CAS Registry Number.

THERMAL REARRANGEMENT OF PYRIDINIUM ANHYDROBASES: MIGRATION OF N-SUBSTITUENTS TO METHINE CARBON
Katritzky, Alan R.,Awartani, Radi
, p. 2505 - 2512 (2007/10/02)
N-Benzyl and N-methyl groups migrate to the methine carbon atom on thermolysis of pyridinium anhydrobases.Cross-over experiments indicate an intermolecular reaction, probably involving homolysis.
