Check Digit Verification of cas no

The CAS Registry Mumber 49764-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,6 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49764-18:
(7*4)+(6*9)+(5*7)+(4*6)+(3*4)+(2*1)+(1*8)=163
163 % 10 = 3
So 49764-18-3 is a valid CAS Registry Number.

Oxidative alkylation of azoles: VII. Adamantylation of azoles via oxidative generation of 1-adamantyl cations

Tsypin,Pevzner,Golod

, p. 1762 - 1766 (2001)

A procedure has been developed for oxidative N-adamantylation of azoles with 1-iodoadamantane in the presence of chromium(IV) oxide or iodine(V) oxide. The procedure is applicable to azoles whose pKBH+ value does not exceed 2.26. * For communication VI, see [1].

Reactions of copper(II) β-diketonates under free radical conditions. Preparation of highly congested β-diketones

Lloris, Maria E.,Galvez, Nicanor,Marquet, Jorge,Moreno-Manas, Marcial

, p. 8031 - 8042 (2007/10/02)

Copper(II) β-diketonates react with alkyl bromides under free radical conditions to give highly congested β-diketones such as 3-(1-adamantyl)-3-alkylpentane-2,4-diones. Another typical free radical reagent: benzoyl peroxide, reacts also functionalizing the intercarbonyl positions.
