Check Digit Verification of cas no
The CAS Registry Mumber 1190376-24-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,3,7 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1190376-24:
(9*1)+(8*1)+(7*9)+(6*0)+(5*3)+(4*7)+(3*6)+(2*2)+(1*4)=149
149 % 10 = 9
So 1190376-24-9 is a valid CAS Registry Number.

Synthesis and optical properties of novel D-π-A-π-D type cationic cyclopentadienyliron complexes of arenes
Zhao,Li,Shi,Zhang,Wang
, p. 54749 - 54756 (2015)
Diphenylethynyl chromophores were successfully introduced into the arene ligands of cationic cyclopentadienyliron complexes through nucleophilic substitution and Suzuki coupling reactions. Three novel cationic cyclopentadienyliron complexes with symmetrical di(4-methoxy-phenylethynyl) chromophores (CFSs) were obtained and completely characterized by IR, 1H NMR, 13C NMR, and MS. The linear and nonlinear optical properties of the obtained molecules were tuned using phenylethynyl linkages. The UV-Vis absorption spectra showed that increasing the conjugation by substituting phenylacetylene spacer resulted in a red shift in the absorption bands and a stronger absorption in CFSs than in the previously reported (η6-cumene)(η5-cyclopentadienyl)iron hexafluorophosphate (I-261). These cross-conjugated D-π-A-π-D type compounds also showed larger third-order nonlinear susceptibility than I-261.
