1040504-85-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1040504-85-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,5,0 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1040504-85:
(9*1)+(8*0)+(7*4)+(6*0)+(5*5)+(4*0)+(3*4)+(2*8)+(1*5)=95
95 % 10 = 5
So 1040504-85-5 is a valid CAS Registry Number.

The use of a single derivative in the configurational assignment of ketone cyanohydrins

Louzao, Iria,Seco, Jose M.,Quinoa, Emilio,Riguera, Ricardo

experimental part, p. 6520 - 6524 (2011/02/22)

The absolute stereochemistry of ketone cyanohydrins can be easily determined by preparing a single MPA derivative. The comparison of two NMR spectra at different temperatures allows the assignment by just paying attention to the evolution of the cyanohydr

Absolute configuration of ketone cyanohydrins by 1H nmr: The special case of polar substituted tertiary alcohols

Louzao, Iria,Garcia, Rosa,Seco, Jose Manuel,Quinoa, Emilio,Riguera, Ricardo

supporting information; experimental part, p. 53 - 56 (2009/07/04)

The absolute configuration of ketone cyanohydrins can be assigned from analysis of the 1H NMR spectra of the corresponding (R)-and (S)-MPA ester derivatives and use of ΔδRS signs. This is an application of the NMR methodology for ste
