Check Digit Verification of cas no

The CAS Registry Mumber 1487-82-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1487-82:
97 % 10 = 7
So 1487-82-7 is a valid CAS Registry Number.

, p. 334 - 338 (2007/10/02)

The average unit cell of the methanol solvate *C14H8N4*2CH3OH, Mr = 589.22 is triclinic, P, a = 8.539(3), b = 8.937(3), c = 9.418(3) Angstroem, α = 103.39(3), β = 100.12(2), γ = 105.39(2) deg, V = 652,2 Angstroem3, Z = 1, dc = 1.50 g cm-3, final Rw=0.050 for 1580 observed independent reflections.Satellite reflections hint at a modulation of the structure in the ac plane.Mixed stacks of alternating and mainly neutral metal complex and Me2tcnq molecules are formed.Crystals grown with electrochemical reduction show a weak activated paramagne tism, those grown without electrochemical support are diamagnetic. - Keywords: Charge Transfer Compound, Mixed Stacks, Modulated Structure


Russkikh, V. S.,Abashev, G. G.

, p. 742 - 745 (2007/10/02)

The synthesis of 2-methyl-, 2,5-dimethyl-, and 2-isopropyl-7,7'-8,8'-tetracyanoquinodimethanes was realized from 2-methyl-, 2,5-dimethyl-, and 2-isopropyl-1,4-cyclohexanediones.These cyclic diketones are obtained with good yields by the Birch reduction of 2-chloromethyl-, 2,5-dichloromethyl-, and 2-isopropyl-1,4-dimethoxybenzenes.
