Calculate Digit Verification of CAS Registry Number 17197-37:
(7*1)+(6*7)+(5*1)+(4*9)+(3*7)+(2*3)+(1*7)=124
124 % 10 = 4
So 17197-37-4 is a valid CAS Registry Number.

REGIOSPECIFIC SYNTHESIS OF AROMATIC COMPOUNDS VIA ORGANOMETALLIC INTERMEDIATES. II. 1,3,5-(TRIMETHYLMETAL(IV))BENZENE COMPOUNDS

Chen, Grace J.,Tamborski, Christ

, p. 149 - 158 (2007/10/02)

Sequential metal-halogen exchange reactions between n-C4H9Li and 1,3,5-tribromobenzene and reaction at each step with (CH3)3MIVCl(MIV = Si, Ge, Sn) has provided a 1,3,5-(trimethylmetal(IV))benzene compound.This class of compounds can be synthesized either trough a step-wise procedure, where the various intermediates are isolated, or in a continuous metal-halogen exchange process without isolation of various intermediates.
