72437-42-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72437-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,3 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72437-42:
(7*7)+(6*2)+(5*4)+(4*3)+(3*7)+(2*4)+(1*2)=124
124 % 10 = 4
So 72437-42-4 is a valid CAS Registry Number.

Hydroxyl radical as a strong electrophilic species

Marusawa, Hiroshi,Ichikawa, Kazuhiko,Narita, Nozomu,Murakami, Hiromu,Ito, Keiichi,Tezuka, Takahiro

, p. 2283 - 2290 (2007/10/03)

In order to clarify an index which could be used as proof of the presence of hydroxyl radical, a new standard isomer distribution ratio of phenols formed from aromatic hydroxylation with [(4-bromophenyl)diazenyl](phenyl)methyl hydroperoxide 4, which is a stable source of hydroxyl radical, under a new appropriate photolysis condition in the presence or absence of benzoquinones is reported. We also demonstrated the strong electrophilic properties of hydroxyl radical in reference to earlier results of electron density calculations.
