Check Digit Verification of cas no

The CAS Registry Mumber 76191-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76191-51:
(7*7)+(6*6)+(5*1)+(4*9)+(3*1)+(2*5)+(1*1)=140
140 % 10 = 0
So 76191-51-0 is a valid CAS Registry Number.

Regioselective lactonization of naphthoquinones: Synthesis and antitumoral activity of the WS-5995 antibiotics

Qabaja, Ghassan,M. Perchellet, Elisabeth,Perchellet, Jean-Pierre,Jones, Graham B.

, p. 3007 - 3010 (2007/10/03)

An acid promoted quinolactonization of naphthoquinones has been developed, providing direct access to either ortho or para isomers as desired. Application of this methodology in syntheses of the antibiotics WS- 5995A, WS-5995C and functional analogs is demonstrated. Preliminary antitumoral activity of the analogs is presented together with electrochemical analysis. (C) 2000 Elsevier Science Ltd.

THE TOTAL SYNTHESIS OF THE ANTI-COCCIDIAL AGENTS WS-5995

McKenzie, Thomas C.,Choi, Woo-Baeg

, p. 1523 - 1532 (2007/10/02)

A total synthesis of the three anti-coccidial agents WS-5995 A, B, and C by a Diels-Alder route is described.An intramolecular lactonization involving the displacement of a chlorine atom on a napthoquinone was the key step in the synthesis of A.
