Check Digit Verification of cas no

The CAS Registry Mumber 253310-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,3,1 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 253310-71:
(8*2)+(7*5)+(6*3)+(5*3)+(4*1)+(3*0)+(2*7)+(1*1)=103
103 % 10 = 3
So 253310-71-3 is a valid CAS Registry Number.

Self-assembly of pyrazolyl based ligands and silver cation into metallamacrocycles and tubular coordination networks

Loi, Marielle,Hosseini, Mir Wais,Jouaiti, Abdelaziz,De Cian, Andre,Fischer, Jean

, p. 1981 - 1985 (2007/10/03)

The 2,6-bis(pyrazolyl)pyrazine ligand 1 forms a 2,2- metallamacrocycle 3, composed of two ligands and two cations, in the presence of the Ag+ cation. In the crystalline phase, the 1,3,5-tris(pyrazolyl)benzene ligand 2 leads to an infinite metallatubular network in the presence of the Ag+ cation, composed of the 2,2-metallamacrocycle 4, which is formed from two molecules of 2 and two cations. This infinite network is formed by double interconnection of consecutive metallamacrocycles through binding of Ag+ centers by the free pyrazolyl moieties.
