Check Digit Verification of cas no
The CAS Registry Mumber 6074-84-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,7 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6074-84:
(6*6)+(5*0)+(4*7)+(3*4)+(2*8)+(1*4)=96
96 % 10 = 6
So 6074-84-6 is a valid CAS Registry Number.

LiTa9O13(OEt)20·2EtOH (I) is a side product of the electrochemical synthesis of Ta(OEt)5 carried out using LiCl as a supporting electrolyte. This product crystallizes in a minor yield upon the storage of crude liquid Ta(OEt)5. Treatment of I with a hot ethanol solution of LiOEt yields Li8Ta8O 14(OEt)20·12EtOH (II). The structures of I and II have been determined using X-ray crystallography. Molecule I, LiTa 9H(μ3-O)4(μ-O)9(μ-OEt) 6(OEt)15(EtOH), is located on a threefold axis that passes through the lithium atom, which coordinates one disordered solvation ethanol molecule and three μ3-oxo groups belonging to the [Ta 6O6(OR)15] ring fragment made of six octahedra. The next layer is formed by the [Ta3O7(OR)6] fragment made of three octahedra linked to the previous fragment through six μ-oxo ligands. In molecule II, Li8Ta8H 8(μ4-O)2(μ3-O) 8(μ-O)4(μ3-OEt)2(μ-OEt) 10(OEt)16·4EtOH, one can distinguish two groups of four [TaO6] octahedra that form [Ta4] tetrahedra sharing two vertices represented by μ4-oxo groups. Four Li atoms are located between the [Ta4] tetrahedra thus forming a interlayer comprising two distorted [LiO4] tetrahedra and two distorted [LiO5] tetragonal pyramids. The other four tetrahedrally coordinated Li atoms are located on the periphery of the molecule and are linked through [O(OR)] edges with Ta atoms. Each Ta atom coordinates three terminal OR groups and one μ-OR group. Four solvation ethanol molecules are hydrogen-bonded with the terminal OR groups at Ta atoms.
