Check Digit Verification of cas no

The CAS Registry Mumber 132156-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,5 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132156-41:
(8*1)+(7*3)+(6*2)+(5*1)+(4*5)+(3*6)+(2*4)+(1*1)=93
93 % 10 = 3
So 132156-41-3 is a valid CAS Registry Number.

Syntheses and NMR Spectra of Substituted 2-tert-Butyladamantan-2-ols

Duddeck, Helmut,Rosenbaum, Doris

, p. 1700 - 1707 (2007/10/02)

The synthesis of a number of substituted 2-tert-butyladamantan-2-ols from the corresponding ketones is described.In addition to these addition reactions, some unexpected rearrangements were observed.Reaction mechanisms are proposed to rationalize the experimental results. 13C NMR spectra of some adamantanes are discussed in terms of substituent interaction effects.
