Check Digit Verification of cas no

The CAS Registry Mumber 58851-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,5 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 58851-76:
(7*5)+(6*8)+(5*8)+(4*5)+(3*1)+(2*7)+(1*6)=166
166 % 10 = 6
So 58851-76-6 is a valid CAS Registry Number.

Synthesis of anthracyclinone precursor: 5,12-dihydroxy-1,3,4- trihydronaphthacene-2,6,11-quinone

Tririya, Gasirat,Zanger, Murray

, p. 3047 - 3059 (2007/10/03)

Two practical and efficient approaches for preparing large quantities of 5,12-dihydroxy-1,3,4-trihydronaphthacene-2,6,11-quinone 9 are described. Both synthetic approaches involve a simple route with a fewer number of steps and utilize readily available and inexpensive starting materials. Large-scale production of this precursor may prove to be useful for further research involving the synthesis of antineoplastic anthracyclines and development of their analogs with increased activity and decreased toxicity.
