74457-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74457-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74457-59:
(7*7)+(6*4)+(5*4)+(4*5)+(3*7)+(2*5)+(1*9)=153
153 % 10 = 3
So 74457-59-3 is a valid CAS Registry Number.

MICELLAR CATALYSIS IN THE BASE-CATALYZED AUTOOXIDATION OF DIOSPHENOL
Utaka, Masanori,Matsushita, Seishiro,Yamasaki, Haruhiro,Takeda, Akira
, p. 1063 - 1064 (2007/10/02)
The base-catalyzed autooxidation of diosphenol was catalyzed by cationic micelles with a remarkable selectivity to give an 1,5-keto acid by a mechanism analogous to the oxygenation of quercetin or 3-hydroxyflavones.
