Check Digit Verification of cas no

The CAS Registry Mumber 368862-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,6,8,8,6 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 368862-89:
(8*3)+(7*6)+(6*8)+(5*8)+(4*6)+(3*2)+(2*8)+(1*9)=209
209 % 10 = 9
So 368862-89-9 is a valid CAS Registry Number.

Metal Complexes of Molecular Clefts. The Synthesis and X-Ray Crystal Structures of a Mononuclear Barium and Four Binuclear Silver(I) Complexes of Bibracchial Tetraimine Schiff-base Macrocycles

Adams, Harry,Bailey, Neil A.,Carlisle, W. Daniel,Fenton, David E.,Rossi, Gentilina

, p. 1271 - 1283 (1990)

Mononuclear barium and binuclear silver(I) complexes of bibracchial tetraimine Schiff-base macrocycles L1-L4 derived from the '2+2' condensation of 2,6-diacetylpyridine and the functionalised triamines N,N-bis(2-aminoethyl)-2-(aminomethyl)pyridine, N,N-bis(3-aminopropyl)-2-(aminomethyl)pyridine, N,N-bis(3-aminopropyl)-2-methoxyethylamine, and N,N-(3-aminopropyl)-2-methoxybenzylamine, respectively, have been synthesised.The crystal structures of five complexes have been determined: 1>2 crystallises in the monoclinic space group C2/c (C2h6, no.15) and has unit-cell dimensions a = 20.310(38), b = 14.453(41), c = 15.137(29) Angstroem, β = 104.84(15) deg, and Z = 4; 1>2 crystallises in the tetragonal space group /41cd (C4v12, no.110) with a = 28.11(4), c = 21.618(16) Angstroem, and Z = 16; 2>2*0.5H2O crystallises in the triclinic space group P1 (Ci1, no.2) with a = 12.277(16), b = 13.899(14), c = 15.260(50) Angstroem, α = 77.30(20), β = 70.17(20), γ = 71.29(9) deg, and Z = 2; 3>2*0.5 H2O crystallises in the triclinic space group P1 (Ci1, no.2) with a = 14.171(14), b = 18.323(16), c = 12.495(23) Angstroem, α = 99.20(12), β = 120.13(11), γ = 116.35(7) deg, and Z = 2; 4>2 crystallises in the monoclinic space group P21/a (C2h5, no.14), a = 16.595(16), b = 13.363(11), c = 23.951(25) Angstroem, β = 105.43(8) deg, and Z = 4.The macrocycles fold to present molecular clefts into which the metals co-ordinate.Modification of the ring size and of the nature of the donor atom in the pendant arm leads to the Ag...Ag separation in the binuclear silver(I) complexes varying from 2.9 to 6.9 Angstroem.
