Check Digit Verification of cas no

The CAS Registry Mumber 1569868-47-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,8,6 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1569868-47:
(9*1)+(8*5)+(7*6)+(6*9)+(5*8)+(4*6)+(3*8)+(2*4)+(1*7)=248
248 % 10 = 8
So 1569868-47-8 is a valid CAS Registry Number.

Empirical and theoretical insights into the structural features and host-guest chemistry of M8L4 tube architectures

We demonstrate a general method for the construction of M8L 4 tubular complexes via subcomponent self-assembly, starting from CuI or AgI precursors together with suitable elongated tetraamine and 2-formylpyridine subcomponents. The tubular architectures were often observed as equilibrium mixtures of diastereomers having two different point symmetries (D2d or D2 a? D4) in solution. The equilibria between diastereomers were influenced through variation in ligand length, substituents, metal ion identity, counteranion, and temperature. In the presence of dicyanoaurate(I) and AuI, the D 4-symmetric hosts were able to bind linear Au(Au(CN) 2)2- (with two different configurations) as the best-fitting guest. Substitution of dicyanoargentate(I) for dicyanoaurate(I) resulted in the formation of Ag(Au(CN)2)2- as the optimal guest through transmetalation. Density functional theory was employed to elucidate the host-guest chemistries of the tubes.
