Check Digit Verification of cas no

The CAS Registry Mumber 138006-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,0 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138006-16:
(8*1)+(7*3)+(6*8)+(5*0)+(4*0)+(3*6)+(2*1)+(1*6)=103
103 % 10 = 3
So 138006-16-3 is a valid CAS Registry Number.

Charge-transfer complexes of 2,3-dichloro-5,6-dicyanobenzoquinone with imidazole and some aminoacid donors

Shoukry, M. M.,Koussini, R.

, p. 465 - 468 (2007/10/02)

Charge-transfer complexes of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) with some selected electron donors such as imidazole and amino acids have been studied.Electrolytic conductance, potentiometric and spectrophotometric data have allowed the composition, structure and stability of the complexes with the ligands to be deduced.It is found that the DDQ forms 1:1 complexes with the ligands studied.The imidazole complex was synthesized and characterized by microanalysis and IR spectra. Keywords: charge-transfer complexes, 2,3-dichloro-5,6-dicyanobenziquinone, aminoacids, imidazole
