The CAS Registry Mumber 173428-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,2 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173428-06:
(8*1)+(7*7)+(6*3)+(5*4)+(4*2)+(3*8)+(2*0)+(1*6)=133
133 % 10 = 3
So 173428-06-3 is a valid CAS Registry Number.

Control of intermolecular porphyrin π-π interactions: Low-melting liquid-crystal porphyrins with calamitic mesophases

Wang, Qing Min,Bruce, Duncan W.

, p. 2505 - 2506 (1996)

By control of intermolecular π-π interactions using 'flyover' chains, calamitic nematic mesophases are observed in 5,15-disubstituted zinc porphyrins with greatly reduced melting and clearing points.
