Check Digit Verification of cas no

The CAS Registry Mumber 137106-06-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,0 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137106-06:
(8*1)+(7*3)+(6*7)+(5*1)+(4*0)+(3*6)+(2*0)+(1*6)=100
100 % 10 = 0
So 137106-06-0 is a valid CAS Registry Number.

Fluoronaphthyridines and -quinolines as Antibacterial Agents. 5. Synthesis and Antimicrobial Activity of Chiral 1-tert-Butyl-6-fluoro-7-substituted-naphthyridones

Cesare, P. Di,Bouzard, D.,Essiz, M.,Jacquet, J. P.,Ledoussal, B.,et al.

, p. 4205 - 4213 (1992)

A series of novel 7-substituted-1-tert-butyl-6-fluoronaphthyridone-3-carboxylic acids has been prepared.These derivatives are characterized by chiral aminopyrrolidine substituents at the 7 position.In this paper we report the full details of the asymmetric synthesis of this series of compounds.Structure-activity relationship studies indicate that the absolute stereochemistry at the asymmetric centers of the pyrrolidine ring is critical for maintaining good activity.Compounds 60 and 61 (3-amino-4-methylpyrrolidine enantiomers) were selected for preclinical evaluation.
