68748-92-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68748-92-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,7,4 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68748-92:
(7*6)+(6*8)+(5*7)+(4*4)+(3*8)+(2*9)+(1*2)=185
185 % 10 = 5
So 68748-92-5 is a valid CAS Registry Number.

Low-temperature x-ray structural studies of the ester and ether derivatives of cis- and trans-4-tert-butyl cyclohexanol and 2-adamantanol: Application of the variable oxygen probe to determine the relative σ-donor ability of C-H and C-C bonds

Spiniello, Marisa,White, Jonathan M.

, p. 3094 - 3101 (2007/10/03)

Results of low-temperature X-ray structural studies for five cis-, and three trans-4-tert-butyl cyclohexanol, and six 2-adamantanol ester and ether derivatives are reported. Plots of C-OR bond distance against pKa(ROH) for derivatives of axial alcohol (5), equatorial alcohol (6) and 2-adamantanol derivatives (7) give slopes of -2.77 × 10-3, -2.86 × 10-3 and -3.05 × 10-3, respectively. Given that the relative differences in the slopes are modest, no clear distinction can be made about the relative σ-donor ability of a C-H bond and a C-C bond.

Hypobetalipoproteinemic agents. II. Compounds related to 4-(1- adamantyloxy)aniline

Lednicer,Heyd,Emmert,et al.

, p. 69 - 77 (2007/10/06)

While the previously used displacement reaction of sodium 1-adamantyl oxide on 4-fluoronitrobenzene was applicable to the preparation of 4-(1-adamantyloxy) aniline and several related compounds, certain derivatives were not easily accessible by this route
