Check Digit Verification of cas no

The CAS Registry Mumber 50405-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,4,0 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50405-75:
(7*5)+(6*0)+(5*4)+(4*0)+(3*5)+(2*7)+(1*5)=89
89 % 10 = 9
So 50405-75-9 is a valid CAS Registry Number.

The chemistry of antimicrobially active 1-hydroxy-2-pyridones

Lohaus,Dittmar

, p. 1311 - 1316 (2007/10/02)

The unsaturated δ-keto esters obtained by condensation of acid chlorides with esters of di- or trialkyl-acrylic acids can be cyclized with hydroxylamine to yield 1-hydroxy-2-pyridones. However, in many cases a two-steps synthesis may be of advantage in preparative respect, the ketoesters being cyclized to 2-pyrones, which then are reacted with hydroxylamine in the presence of certain bases to give. The hydroxy-pyridones show pronounced antifungal activity in vitro as well as in experimental guinea pig dermatophytosis.
