Check Digit Verification of cas no

The CAS Registry Mumber 17711-27-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,1 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17711-27:
(7*1)+(6*7)+(5*7)+(4*1)+(3*1)+(2*2)+(1*7)=102
102 % 10 = 2
So 17711-27-2 is a valid CAS Registry Number.

Synthesis and evaluation of phenyl substituted sydnones as potential DPPH-radical scavengers

Mallur, Shanta G.,Tiwari,Raju, B. China,Babu, K. Suresh,Ali, A. Zehra,Sastry,Rao, J. Madhusudana

, p. 1686 - 1689 (2008/09/19)

A series of phenyl substituted sydnones has been synthesized and their radical-scavenging activity has been studied on DPPH free radical. Out of eighteen compounds screened, nine compounds show interesting activity. A mechanism is presented whereby sydnones scavenge DPPH radical through donating H-atom at 4th-position. Its strong radical-scavenging activity mainly arises from 1, 2, 3-oxadiazolium-5-olate ring. Different substituents and their positions on the phenyl ring differently influence DPPH scavenging activity and therefore, may provide clues to design and develop better free-radical scavenging sydnones with multiple activities.
