Check Digit Verification of cas no

The CAS Registry Mumber 201941-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,9,4 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 201941-71:
(8*2)+(7*0)+(6*1)+(5*9)+(4*4)+(3*1)+(2*7)+(1*1)=101
101 % 10 = 1
So 201941-71-1 is a valid CAS Registry Number.

Metal complexes of dyes. X: New transition metal complexes of anthraquinone dyes

Kuehlwein, Frank,Polborn, Kurt,Beck, Wolfgang

, p. 1931 - 1944 (2008/10/09)

The chloro-bridged compounds [(R3P)MCl2]2 (M = Pd, Pt; R = ethyl, phenyl, n-butyl), [(Ph3P)2PdCl]2(BF4)2, [(η5-C5Me5)MCl2]2 (M = Rh, Ir), [(η6-p-cymene)RuCl2]2, [(η5-C5H5)Fe(η5-C 5H3)CH2N(CH3)2PdCl] 2 react with mono-and dianions of several 9,10-anthracene-dione dyes [1-amino-9,10-anthracene-dione, Disperse Blue 19 (1-amino-4-aniline-9,10-anthracene-dione), 1,4-diamino-9,10-anthracenedione, Solventgreen 3 [1,4-bis(4′-methylaniline)-9,10-anthracene-dione], dianthrimide [1,1′-dianthraquinonylamin], 1-azo-β-naphtol-9,10-anthracene-dione, 1-anilido-o-carboxy-9,10-anthracene-dione and Quinizarin (1,4-dihydroxy-9,10-anthracene-dione)] to give N,O-, O,O-and O,N,O-chelate complexes. Copper(II)-and palladium(II) acetate and the anion of 1-aminoanthraquinone afford N,O-bischelates. Spectroscopic data are discussed. In comparison to the free anthraquinones the dye complexes show a bathochromic shift in the UV/VIS spectra. The structures of (ethyl)3P(Cl)Pt(1-aminoanthraquinone-H+), (η-C5Me 5)(Cl)Ir(1-azo-β-naphtolanthraquinone-H+) and (η-C5Me5)Rh(1-anilido-o-carboxyanthraquinone-2H +) were determined by X-ray diffraction.
