7442-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7442-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,4 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7442-21:
89 % 10 = 9
So 7442-21-9 is a valid CAS Registry Number.

Origin of the Diastereoselectivity of the Heterogeneous Hydrogenation of a Substituted Indolizine

Cormanich, Rodrigo A.,Zeoly, Lucas A.,Santos, Hugo,Camilo, Nilton S.,Bühl, Michael,Coelho, Fernando

supporting information, p. 11541 - 11548 (2020/10/12)

In this work, the stereoselective heterogeneous hydrogenation of a tetrasubstituted indolizine was studied. Partial hydrogenation products were obtained in three steps from a substituted pyridine-2-carboxaldehyde prepared from commercial pyridoxine hydrochloride. The hydrogenation of the indolizine ring was shown to be diastereoselective, forming trans-6b and cis-9. Theoretical calculations (ab initio and DFT) were used to rationalize the unusual trans stereoselectivity for 6b, and a keto-enol tautomerism under kinetic control has been proposed as the source of diastereoselectivity.
