873-12-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 873-12-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 873-12:
(5*8)+(4*7)+(3*3)+(2*1)+(1*2)=81
81 % 10 = 1
So 873-12-1 is a valid CAS Registry Number.

Polyspiranes, 16. - Cascade Rearrangements, 11. - Synthesis, Structure, Conformation, and Dynamics of Heptacyclo1,5.05,9.09,13.013,17.017,21>tetracosane (Coronane)

Wehle, Detlef,Schormann, Norbert,Fitjer, Lutz

, p. 2171 - 2178 (2007/10/02)

Coronane (2) was synthesized by addition of allylmagnesium bromide to ketone 7, rearrangement of the resulting homoallyl alcohol 8a to diene 9, hydrozirconization of 9 followed by bromination to give 11, and finally radical cyclization of 11.A direct cyclization of 9 using tri(n-butyl)tin hydride failed. 2 is all-cis-configurated, adopts a chair conformation in the crystal state and in solution and exhibits an extremely low barrier of inversion (ΔG(excit.)173 /= 8.6 kcal/mol).
