4378-33-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4378-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4378-33:
(6*4)+(5*3)+(4*7)+(3*8)+(2*3)+(1*3)=100
100 % 10 = 0
So 4378-33-0 is a valid CAS Registry Number.

Fenbufen, a new anti inflammatory analgesic: synthesis and structure activity relationships of analogs

Child,Osterberg,Sloboda,Tomcufcik

, p. 466 - 476 (2007/10/05)

100 analogs of fenbufen were prepared and tested using the carrageenan, polyarthritis, and UV erythema anti inflammatory tests and the 2 phenyl 1,4 benzoquinone writhing and inflamed paw pressure analgesic tests. Only 3 retained the same full spectrum of activity as fenbufen: dl 4 (4 biphenylyl) 4 hydroxybutyric acid, dl 4 (4 biphenylyl) 1,4 butanediol, and 4 biphenylacetic acid. Fenbufen had the same spectrum of activity as aspirin, phenylbutazone, and indomethacin in the 5 tests. In addition, dose response derived potencies show fenbufen more potent than aspirin and at least as potent as phenylbutazone in all 5 tests. Two related compounds were generally similar.
