Check Digit Verification of cas no
The CAS Registry Mumber 138946-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,4 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138946-36:
(8*1)+(7*3)+(6*8)+(5*9)+(4*4)+(3*6)+(2*3)+(1*6)=168
168 % 10 = 8
So 138946-36-8 is a valid CAS Registry Number.

The synthesis and X-ray measurements of four Schiff bases were carried out at 100K. The HOMA and HOSE aromaticity indices wer estimated on the basis of the experimental data. The aromaticity of the phenyl ring and the chelate chain was analysed. A comparison of the aromaticity of naphthalene and phenyl derivatives of hydroxy aryl Schiff bases is presented. The balance between the aromaticity of adjacent rings of the naphthalene fragment and its effect on proton transfer is defined. Research on the interrelations between aromaticity and the intramolecular proton transfer in hydroxy aryl Schiff bases is shown. Copyright
