Check Digit Verification of cas no

The CAS Registry Mumber 73267-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,6 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 73267-93:
(7*7)+(6*3)+(5*2)+(4*6)+(3*7)+(2*9)+(1*3)=143
143 % 10 = 3
So 73267-93-3 is a valid CAS Registry Number.

Trinuclear, tetranuclear, and polymeric CuII complexes from the first use of 2-pyridylcyanoxime in transition metal chemistry: Synthetic, structural, and magnetic studies

The first use of 2-pyridylcyanoxime, (py)C(CN)-NOH, in transition metal chemistry is described. Depending on the nature of the metal starting material and the reaction conditions employed, the CuII/(py)C(CN)NOH system has provided access to complexes [Cu3O{(py)C(CN)NO} 3(NO3)-(H2O)2(MeOH)] (1), [Cu 4O{(py)C(CN)NO}4(O2CMe)2] (2), [Cu4(OH)2{(py)C(CN)NO}2(O2CPh) 4]2n·n[Cu4(OH)2-{(py)C(CN)NO} 2(O2CPh)4](3), and [Cu{(py)C(CN)NO} 2]n (4). The molecule of 1 consists of three Cu II atoms in a strictly equilateral arrangement bridged by a central μ3-oxide group. The molecule of 2 consists of a tetrahedron of CuII atoms held together by a central μ4-oxide ion, four η1:η1:η1;;μ-(py)C(CN) NO- ligands and two η1:η1;;μ- MeCO2- groups. The crystal structure of 3 consists of [Cu4(OH)2{(py)C(CN)NO}2(O2CPh) 4]2n double chains and discrete cluster [Cu 4(OH)2{(py)C(CN)NO}2-(O2CPh) 4] molecules. The crystal structure of 4 consists of neutral polymeric chains based on centrosymmetric mononuclear [Cu{(py)C(CN)NO} 2] units. The CuII atoms are doubly bridged by the oximate groups of two η1:η1:η1:μ-(py) C(CN)NO- ligands. Variable-temperature, solid-state direct current (dc) magnetic susceptibility studies were carried out for 1-4. The data indicate very strong antiferromagnetic exchange interactions for 1-3. The obtained J values are discussed in depth on the basis of the structural parameters of the complexes, literature reports, and existing magnetostructural correlations.
