Check Digit Verification of cas no

The CAS Registry Mumber 777862-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,7,8,6 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 777862-18:
(8*7)+(7*7)+(6*7)+(5*8)+(4*6)+(3*2)+(2*1)+(1*8)=227
227 % 10 = 7
So 777862-18-7 is a valid CAS Registry Number.

Hydrogen-bond mediation of supramolecular aggregation in neutral bis-(C6F5)Pt complexes with aromatic H-bond donating ligands. A synthetic and structural study

Casas, Jose M.,Diosdado, Beatriz E.,Falvello, Larry R.,Fornies, Juan,Martin, Antonio,Rueda, Angel J.

, p. 2733 - 2740 (2007/10/03)

Six pentafluorophenylplatinum(II) complexes containing proton acceptor atoms (F) and pyridine-like aromatic ligands able to act as proton donors have been synthesized and characterized, with emphasis on the factors that mediate their supramolecular aggregation in the solid state - hydrogen bonds and π-π interactions. The crystal structure analyses of the mononuclear complexes cis-[Pt(C6F5)2(napy)] (1), cis-[Pt(C6F5)2(CH2napy)] (3), cis-[Pt(C6F5)2(2-ammpy)] (5), and cis-[Pt(C6F5)2(2-bipym)] (6) reveal the influence of D-H...Pt and D-H...F (D = C, N) hydrogen bonding on the organization of molecules into stacks, which can be further interconnected to generate channels. The prevalence of hydrogen bonding over π-π interactions between aromatic rings in establishing the nature of the observed supramolecular aggregation is demonstrated.
