Check Digit Verification of cas no

The CAS Registry Mumber 106259-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,2,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106259-99:
(8*1)+(7*0)+(6*6)+(5*2)+(4*5)+(3*9)+(2*9)+(1*9)=128
128 % 10 = 8
So 106259-99-8 is a valid CAS Registry Number.

TAUTOMERISM OF AZINE DERIVATIVES. 11. 14N-NMR AND 17O-NMR INVESTIGATION OF INTRACHELATE TAUTOMERISM OF ACYLMETHYLPYRIDINES

Lapachev, V. V.,Stekhova, S. A.,Mainagashev, I. Ya.,Fedotov, M. A.,Khall, V. E.,Mamaev, V. P.

, p. 633 - 639 (2007/10/02)

Intrachelate -sigmatropic tautomerism in a series of acylmethylpyridines has been studied by 14N- and 17O-NMR specroscopy.Principles of tautomer modelling or simulation have been proposed and examined, nitrogen ond oxygen chemical shift spectra have been determined, and the accuracy of this method for the determination of tautomer composition has been evaluated.The presence of acceptor (electron withdrawing) substituents in the acylmethyl side-chain fragment has been found to stabilize the NH-tautomer.
