81684-13-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81684-13-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,8 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81684-13:
(7*8)+(6*1)+(5*6)+(4*8)+(3*4)+(2*1)+(1*3)=141
141 % 10 = 1
So 81684-13-1 is a valid CAS Registry Number.

NMR Spectra and Stereochemistry of Perhydrooxazolopyridines

Crabb, Trevor A.,Trethewey, Andrew N.,Takeuchi, Yoshito

, p. 345 - 347 (1988)

Low-temperature 13C and 1H NMR spectra show perhydrooxazolopyridine to exist in CDCl3-CFCl3 solution at 183 K as an equilibrium between 73percent trans-fused and 27percent O-inside cis-fused conformers. cis-(H-1, H-8a)-1-Alkylperhydrooxazolopyridines (alkyl=methyl, ethyl, isopropyl) adopt equilibria heavily biased towards the trans-fused conformers, whereas the epimers adopt 18percent O-inside cis-fused -->/pyridine adopts an equilibrium containing ca 3percent trans-fused conformer in equilibrium with 97percent O-inside cis-fused conformer.
