Check Digit Verification of cas no

The CAS Registry Mumber 2973-43-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2973-43:
(6*2)+(5*9)+(4*7)+(3*3)+(2*4)+(1*3)=105
105 % 10 = 5
So 2973-43-5 is a valid CAS Registry Number.

NONSELECTIVE DISPROPORTIONATION OF ISOMERIC HYDROXYCYCLOHEXADIENYL RADICALS TO PHENOLS

Tezuka, Takahiro,Marusawa, Hiroshi,Ichikawa, Kazuhiko

, p. 2145 - 2148 (2007/10/02)

Comparison of the isomer ratios and yields of cresol, methoxyphenol, and nitrophenol, which were obtained by the aromatic hydroxylation with hydroxyl radical in the presence or absence of benzoquinones in anhydrous media, indicates that disproportionation of hydroxycyclohexadienyl radicals occurs nonselectively.
