Check Digit Verification of cas no

The CAS Registry Mumber 871036-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,0,3 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 871036-89:
(8*8)+(7*7)+(6*1)+(5*0)+(4*3)+(3*6)+(2*8)+(1*9)=174
174 % 10 = 4
So 871036-89-4 is a valid CAS Registry Number.

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.
