Check Digit Verification of cas no

The CAS Registry Mumber 67433-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,3 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67433-82:
(7*6)+(6*7)+(5*4)+(4*3)+(3*3)+(2*8)+(1*2)=143
143 % 10 = 3
So 67433-82-3 is a valid CAS Registry Number.

γ-TRIMETHYLSILYL(TRIPHENYLSILYL)PYRIDINES IN SYNTHESES OF SILICON-CONTAINING PYRIDINIUM YLIDS AND INDOLIZINES

Prostakov, N. S.,Varlamov, A. V.,Saksena, N.,Savina, A. A.,Datta Rai, G.,Maslova, L. V.

, p. 748 - 751 (2007/10/02)

Three N-phenacyl-γ-trimethylsilyl(triphenylsilyl)pyridinium bromides were converted to stable silyl-substituted pyridinium ylids.Six previously unknown silicon-containing indolizines were obtained by two methods, viz., 1,3-dipolar cycloaddition of dimethyl acetylenedicarboxylate (DMAD) to the pyridinium ylids and the Chichibabin reaction.Spectral data that confirm the structures of the synthesized compounds are presented.
