452904-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 452904-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,9,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 452904-90:
(8*4)+(7*5)+(6*2)+(5*9)+(4*0)+(3*4)+(2*9)+(1*0)=154
154 % 10 = 4
So 452904-90-4 is a valid CAS Registry Number.

Self-organized metallo-helicates and -ladder with 2,2′-biphenyldicarboxylate (C14H8O4)2-: Synthesis, crystal structures, and magnetic properties

Kumagai, Hitoshi,Inoue, Katsuya,Kurmoo, Mohamedally

, p. 1283 - 1289 (2002)

We report on the hydrothermal synthesis, single-crystal structures and magnetic properties of three one-dimensional coordination polymers employing the 2,2′-biphenyldicarboxylate dianion, (C14H8O4)2-, as the bridging component. [MII(H2O)4(C14H8 O4)], where M = Co (1) and Ni (2), consist of helical chains of square-planar MII(H2O)4 bridged by C14H8O4 with each carboxylate group acting as a mono-dentate ligand. The magnetic properties are those of paramagnets (1:C = 3.34(1) cm3K/mol, μeff= 5.17 μB, θ = -51(1) K;2: C = 0.985(9) cm3K/mol, μeff = 2.81 μB, θ = +27(2) K) with an antiferromagnetic exchange for 1 and a ferromagnetic exchange for 2. Cu2(C14H8O4) (H2O)2 (3) is composed of tetracarboxylato-dimeric units bridged into ladders by biphenyl units. The ladders are packed parallel to each other, and narrow channels are present due to insufficient space filling of the biphenyl rings. Its magnetic behavior follows that of a Bleaney-Bowers singlet-triplet model with a gap of 470(10) K.
