Check Digit Verification of cas no

The CAS Registry Mumber 15095-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,9 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15095-63:
(7*1)+(6*5)+(5*0)+(4*9)+(3*5)+(2*6)+(1*3)=103
103 % 10 = 3
So 15095-63-3 is a valid CAS Registry Number.

NMR Study of Isolobal N-CH3+, N-BH3 and N-BF3 Imidazole Derivatives

Padilla-Martinez, Itzia Irene,Ariza-Castolo, Armando,Contreras, Rosalinda

, p. 189 - 193 (1993)

Some N-BH3, N-BF3, N+-CH3 and N+-H imidazole derivatives have been prepared and their 13C, 11B and 1H NMR spectra studied.The effect of the different substituents was analysed.The isolobal character of the N-BH3 and N-CH3 derivatives is reflected in their spectra.In the 13C-H coupled spectra of N-borane adducts, the hydrides appear to be coupled with the heterocyclic carbon atoms.The C-4 chemical shift value is indicative of the nature of the N-substitution; lone pair (128-130 ppm), BH3 (126-128 ppm), BF3 and + (122-124 ppm) or + (117-119 ppm).The latter values allowed the chemical shifts of frozen imidazole to be estimated; 128 ppm for C-4 and 117 for C-5.Key-Words: Imidazole-BH3, Imidazole-BF3, 1H, 11B and 13C NMR, Longe-range J(C,H) values
