Check Digit Verification of cas no
The CAS Registry Mumber 479-22-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 479-22:
(5*4)+(4*7)+(3*9)+(2*2)+(1*2)=81
81 % 10 = 1
So 479-22-1 is a valid CAS Registry Number.

Structures of Charge-Perturbed Molecules, 47. Disodium and Dipotassium Nitranilates: The Cyanine Distortion of the Six-Membered Carbon Ring

Crystals of lemon yellow dipotassium nitranilate and of yellow disodium nitranilate dihydrate have been grown and their structures determined at 290 and 200 K.The six-membered.O2N-disubstituted rings show a pronounced cyanine distortion with all four CO bonds identical and the two (OCC(NO2)CO)(1-) chains connected by single CC bonds of each 156 pm length.In the anhydrous K(1+) salt, the ring is planar, but in the Na(1+) hydrate salt it exhibits a twist conformation.Quantum chemical calculations allow to reproduce the structure in every detail, demonstrate strong charge alternation along the cyanine with considerable delocalozation into the O2N acceptor substituents, and suggest that the rather long connecting CC bonds contain positively charged carbon centers on both ends.In addition, metal ion coordination effects as well as the rather high pKa value of nitranilic acid are rationalized. - Keywords: Cyanine Distortion of C6-Rings, Single Crystal Structures, Semiempirical Calculations
