143318-11-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143318-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,1 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143318-11:
(8*1)+(7*4)+(6*3)+(5*3)+(4*1)+(3*8)+(2*1)+(1*1)=100
100 % 10 = 0
So 143318-11-0 is a valid CAS Registry Number.

Fragmentation Selectivity in Electron Impact Ionization Mass Spectra of Substituted Dimethoxybenzenes
Nakata, Hisao,Jitsukawa, Fumie,Toyama, Hitomi,Kato, Yuko
, p. 720 - 723 (1992)
Several 1-X-substituted-3-methoxy-4-trideuteromethoxybenzenes were synthesized and their electron impact ionization mass spectra were measured with an ionizing energy of 20 eV.From the peak intensity ratio of and the fragmentation-dire
