778595-97-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 778595-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,5,9 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 778595-97:
(8*7)+(7*7)+(6*8)+(5*5)+(4*9)+(3*5)+(2*9)+(1*7)=254
254 % 10 = 4
So 778595-97-4 is a valid CAS Registry Number.

Exo-π-bonding to an ortho-carborane hypercarbon atom: Systematic icosahedral cage distortions reflected in the structures of the fluoro-, hydroxy- and amino-carboranes, 1-X-2-Ph-1,2-C2B10H 10 (X = F, OH or NH2) and related anions

, p. 2786 - 2799 (2007/10/03)

The structures of derivatives of phenyl-ortho-carborane bearing on the second cage hypercarbon atom a π-donor substituent (F, OH, O-, NH2, NH- and CH2-) were investigated by NMR, X-ray crystallography and computational studies. The molecular structures of these compounds, notably their cage C1-C2 distances and the orientations of their π-donor substituents (OH, NH2, NH - and CH2-) show remarkable and systematic variations with the degree of exo π-bonding, which varies as expected with the π-donor characteristics of the substituent.
