3205-36-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3205-36-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3205-36:
(6*3)+(5*2)+(4*0)+(3*5)+(2*3)+(1*6)=55
55 % 10 = 5
So 3205-36-5 is a valid CAS Registry Number.

Deazetation of a Bicyclic Azo Compound: Resolution of a Stereochemical Ambiguity and Conformational Analysis of a Biradical

Samuel, Christopher J.

, p. 1259 - 1265 (2007/10/02)

Development of a new approach has permitted a fuller analysis of the stereochemistry of deazetation of the stereospecifically deuteriated azo compound (1d) than could be achieved previously, in that it has proved possible to analyse 2H2>octa-1,7-diene for E,E-, E,Z,-and Z,Z-content.This has given results for the thermal and photochemical reactions that can be rationalised in terms of partial conformational equilibration of the biradical.

Struktur eines O,N-Ketenacetals: (1RS,8SR,10SR)4(15)Z)-4-Aethyliden-5-oxa-3-azatricyclo3,8>tetradecan)

Kuemin, Albin,Maverick, Emily,Seiler, Paul,Vanier, Noel,Damm, Lorenz,et al.

, p. 1158 - 1175 (2007/10/02)

Methods for the preparation of a series of model compounds which were required for stereochemical studies are described: the tricyclic O,N-ketenacetal 1, the two diastereomeric bicyclic amino acids 7 and 10 (see Scheme 2), and the two diastereomeric conformationally fixed tetrahydro-1,3-oxazines (=1,3-oxazines) 9 and 11.An x-ray analysis of racemic 1 reveals a quasi-tetrahedral nitrogen pyramid of the O,N-ketene acetal grouping, and an almost perfect conformational analogy between the N- and C-centered allylic positions at the double bond.
