Check Digit Verification of cas no

The CAS Registry Mumber 106587-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,5,8 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 106587-52:
(8*1)+(7*0)+(6*6)+(5*5)+(4*8)+(3*7)+(2*5)+(1*2)=134
134 % 10 = 4
So 106587-52-4 is a valid CAS Registry Number.

Chromatographic Separation of Enantiomers and Barriers to Enantiomerization of Axially Chiral Aromatic Carboxamides

Cuyegkeng, Maria Assunta,Mannschreck, Albrecht

, p. 803 - 810 (2007/10/02)

The enantiomers (M) and (P) of a series of similar aromatic carboxamides have been, for the first time, investigated analytically and enriched preparatively by liquid chromatography on triacetylcellulose.Enantiomeric purities (7-99percent), specific rotations, and barriers to rotation about the C(sp2)-C(sp2) bond (87 - 120 kJ/mol, Table 5) were determined.These energies are discussed in terms of the size of ortho substituents and of the buttressing effects by meta substituents.
