Check Digit Verification of cas no

The CAS Registry Mumber 105448-94-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,4,4 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105448-94:
(8*1)+(7*0)+(6*5)+(5*4)+(4*4)+(3*8)+(2*9)+(1*4)=120
120 % 10 = 0
So 105448-94-0 is a valid CAS Registry Number.

13C NMR Study of Substituted 10,10-Diphenyl-9-Phenanthrones. Structure Determination and Signal Assignment using 2D NMR Techniques

Mynott, R.,Romao, Maria J.,Herold, B. J.

, p. 1130 - 1133 (1989)

The 13C NMR spectrum of 10,10-diphenyl-9-phenanthrone was assigned unambiguously using 2D 13C,1H shift correlated NMR spectra, optimized either for one-bond or long-range 13C-1H couplings, and 2D RELAY NMR spectra.This information allowed the structures of number of substituted 10,10-diphenyl-9-phenanthrones to be decuded from their 13C NMR spectra.The results provide an insight into the mechanism of the reaction of 9-fluorenone with chlorodiphenylmethyllithium.KEY WORDS - 13C 2D long-range 13C,1H shift correlation 2D RELAY Substituted 9-phenanthrones
