Check Digit Verification of cas no

The CAS Registry Mumber 98454-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98454-42:
(7*9)+(6*8)+(5*4)+(4*5)+(3*4)+(2*4)+(1*2)=173
173 % 10 = 3
So 98454-42-3 is a valid CAS Registry Number.

Hybrid Organo- and Biocatalytic Process for the Asymmetric Transformation of Alcohols into Amines in Aqueous Medium

Liardo, Elisa,Ríos-Lombardía, Nicolás,Morís, Francisco,Rebolledo, Francisca,González-Sabín, Javier

, p. 4768 - 4774 (2017/07/24)

A hybrid organo- and biocatalytic system for the asymmetric conversion of racemic alcohols into amines was developed. Combining an organocatalyst, AZADO, an oxidant, NaOCl, and an enzyme, ω-transaminase, we implemented a one-pot oxidation-transamination sequential process in aqueous medium. The method showed broad substrate scope and was successfully applied to conventional secondary alcohols and sterically hindered β-substituted cycloalkanols, where a highly stereoselective dynamic asymmetric bioamination enabled us to set up both contiguous stereocenters with very high enantio- and diastereomeric ratio (>90% yield, >99% ee, and up to 49:1 dr).
