Check Digit Verification of cas no

The CAS Registry Mumber 693285-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,3,2,8 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 693285-59:
(8*6)+(7*9)+(6*3)+(5*2)+(4*8)+(3*5)+(2*5)+(1*9)=205
205 % 10 = 5
So 693285-59-5 is a valid CAS Registry Number.

A mild oxidation of deactivated naphthalenes and anthracenes to corresponding para-quinones by N-bromosuccinimide

Natarajan, Palani,Vagicherla, Vinuta Devi,Vijayan, Muthana Thevar

, p. 3511 - 3515 (2014)

A new method to synthesize 1,4-naphthoquinone and 9,10-anthraquinone from naphthalene and anthracene functionalized with either -CHO or -COOH groups, using N-bromosuccinimide (NBS) in aqueous N,N-dimethylformamide at 75-80 °C, has been developed. Further, -CN and -CONH2 functionalized naphthalenes and anthracenes can also be transformed into respective para-quinones in a one pot reaction, after successive acid hydrolysis and subsequent reaction with NBS. We believe that the present finding may serve as a valuable alternative to the classical approaches for the synthesis of polycyclic quinones from polyaromatic carbaldehydes through Dakin oxidation followed by further oxidation of the resulting hydroquinone by heavy metal oxides.
