Check Digit Verification of cas no

The CAS Registry Mumber 1040504-91-3 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, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1040504-91:
(9*1)+(8*0)+(7*4)+(6*0)+(5*5)+(4*0)+(3*4)+(2*9)+(1*1)=93
93 % 10 = 3
So 1040504-91-3 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

13C NMR as a general tool for the assignment of absolute configuration

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

supporting information; experimental part, p. 7903 - 7905 (2010/12/19)

13C NMR, alone or in combination with 1H NMR, allows the assignment of the absolute configuration of chiral alcohols, amines, carboxylic acids, thiols, cyanohydrins, sec,sec-diols and sec,sec-aminoalcohols, derivatized with appropriate chiral auxiliaries. This extends the assignment possibilities of NMR to fully deuterated and to nonproton containing compounds.

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
