Check Digit Verification of cas no

The CAS Registry Mumber 629622-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,9,6,2 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 629622-05:
(8*6)+(7*2)+(6*9)+(5*6)+(4*2)+(3*2)+(2*0)+(1*5)=165
165 % 10 = 5
So 629622-05-5 is a valid CAS Registry Number.

Synthesis, conformational analysis and free radical scavenging activity of some new spiropyranoquinolinones.

Panteleon, Vassiliki,Marakos, Panagiotis,Pouli, Nicole,Mikros, Emmanuel,Andreadou, Ioanna

, p. 522 - 529 (2003)

A series of novel spiroadamantyl- and spirocyclical substituted pyranoquinolin-2-ones were synthesized and the conformation of the pyran ring was investigated. The free radical scavenging activity of the synthesized compounds was determined by their interaction with the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). All compounds tested scavenged the DPPH radical and among them derivatives possessing extended conjugation showed the highest activity.
