Check Digit Verification of cas no

The CAS Registry Mumber 149401-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,0 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149401-93:
(8*1)+(7*4)+(6*9)+(5*4)+(4*0)+(3*1)+(2*9)+(1*3)=134
134 % 10 = 4
So 149401-93-4 is a valid CAS Registry Number.

Structural diversity of copper(II) coordination polymers based on tosylated isophthalic ligands

Li, Xinfa,Liu, Qingyan

, p. 1815 - 1820 (2013/09/02)

Two tosylated isophthalic ligands, namely, 5-tosyloxy-isophthalic acid (H2toip) and 5-tosylamino-isophthalic acid (H2taip) were synthesized. Self-assembly of CuII ions with H2toip and H2taip ligands under different reaction conditions (temperature, solvents, and auxiliary ligands) gave rise to three coordination polymers formulated as [Cu(toip)(py)2]n (1), [Cu 6(toip)6(H2O)6]n· 8n(H2O) (2), and [Cu6(taip)6(py) 4(dmf)2]n·n[(dmf)6(MeOH) 2(H2O)2] (3) (py = pyridine, dmf = dimethylformamide). Compound 1 is a one-dimensional (1D) coordination polymeric chain. Compounds 2 and 3 are two-dimensional (2D) coordination networks featuring very similar Kagome lattices based on the interconnection of paddle-wheel [Cu2(COO)4] secondary building units (SBUs) and toip2-/taip2- ligands. However, the arrangement of adjacent Kagome lattices in 2 and 3 are distinct, making them crystallize in different space groups and thereby have different crystal structures. Copyright
