Check Digit Verification of cas no
The CAS Registry Mumber 16897-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,9 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16897-56:
(7*1)+(6*6)+(5*8)+(4*9)+(3*7)+(2*5)+(1*6)=156
156 % 10 = 6
So 16897-56-6 is a valid CAS Registry Number.

3,4-, 4,7- and 1,4,7-Substituted indenyl-TiCl3 complexes: Synthesis and comparison of substituent effects
Wei?, Thomas,Meichel, Eduard,Sachse, Helga,Spange, Stefan,Lang, Heinrich
, p. 1083 - 1094 (2008/10/09)
Me3Si-substituted indenes of type 1-SiMe3-3,4- (CH2)3C9H5 (9), 1-SiMe 3-4-R-7-R′C9H5 (11a, R = R′ = Me; 11b, R = R′ = Ph; 11c, R = Me, R′ = Ph) and 1,1′-(SiMe 3)2-4,7-Me2C9H4 (12) were synthesised as precursors for piano-stool type halfsandwich indenyl-titanium trichloride complexes. Treatment of 9, 11, and 12 with equimolar amounts of TiCU gives the complexes (η5-3,4-(CH2)3C 9H5)TiCl3 (13), (η5-4-R-7- R′C9H5)TiCl3 (14a, R = R′ = Me; 14b, R = R′ = Ph; 14c, R = Me, R′ = Ph), and (η5-1- SiMe3-4,7-Me2C9H4)TiCl3 (15), respectively, with liberation of Me3SiCl. Detailed UV/vis spectroscopic and cyclic voltammetric studies were carried out which allow a comparison of substituent effects in 13-15.
