4839-11-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4839-11-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4839-11:
(6*4)+(5*8)+(4*3)+(3*9)+(2*1)+(1*1)=106
106 % 10 = 6
So 4839-11-6 is a valid CAS Registry Number.

Absolute configuration determination and conformational analysis of (-)-(3s,6s)-3α,6β-diacetoxytropane using vibrational circular dichroism and DFT techniques

Munoz, Marcelo A.,Munoz, Orlando,Joseph-Nathan, Pedro

, p. 234 - 241 (2010)

The absolute configuration of semisynthetic (-)-3α,6β- acetoxytropane 1, prepared from (-)-6β-hydroxyhyoscyamine 2, has been determined using vibrational circular dichroism (VCD) spectroscopy. The vibrational spectra (IR and VCD) were calculated using DFT
