Check Digit Verification of cas no

The CAS Registry Mumber 17557-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,5 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17557-76:
(7*1)+(6*7)+(5*5)+(4*5)+(3*7)+(2*7)+(1*6)=135
135 % 10 = 5
So 17557-76-5 is a valid CAS Registry Number.

Absolute Configuration Assignment from Optical Rotation Data by Means of Biphenyl Chiroptical Probes

Vergura, Stefania,Scafato, Patrizia,Belviso, Sandra,Superchi, Stefano

supporting information, p. 5682 - 5690 (2019/03/17)

A non-empirical approach for the assignment of the absolute configuration of chiral 2-alkyl-substituted carboxylic acids and primary amines by [α]D measurements has been developed. The method requires the conversion of the chiral acids or amines into the corresponding 4,4′-disubstituted biphenylamides or biphenylazepines, respectively. In these derivatives a central-to-axial chirality transfer induces a preferred torsion in the biphenyl moiety revealed by the sign of the biphenyl A band in the ECD spectrum. By 4,4′-substitution on the biphenyl moiety a redshift of the A band is obtained, leading to an increase of its relative contribution to optical rotation. This allows to reliably establish a direct correlation between the [α]D sign, the biphenyl twist and, then, the substrate absolute configuration. This approach thus constitutes a really practical and reliable method to assign the absolute configuration of chiral carboxylic acids and primary amines by simple and straightforward [α]D measurement, readily obtainable by a routine instrumentation like the polarimeter.
