90557-96-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90557-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,5 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90557-96:
(7*9)+(6*0)+(5*5)+(4*5)+(3*7)+(2*9)+(1*6)=153
153 % 10 = 3
So 90557-96-3 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.

The Efficient Synthesis of 3-Arylsydnones Under Neutral Conditions

Applegate, Jacqueline,Turnbull, Kenneth

, p. 1011 - 1012 (2007/10/02)

Various substituted aryl sydnones can be prepared in high yield under mild, neutral conditions by nitrosation of the appropriate aryl glycine with isoamyl nitrite in dimethoxyethane followed by cyclization with trifluoroacetic anhydride.
