Check Digit Verification of cas no

The CAS Registry Mumber 94129-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,2 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 94129-85:
(7*9)+(6*4)+(5*1)+(4*2)+(3*9)+(2*8)+(1*5)=148
148 % 10 = 8
So 94129-85-8 is a valid CAS Registry Number.

Efficient biomimetic-type synthesis of the benzo[a]naphthacenequinone antibiotics G-2A and G-2N

Krohn, Karsten,Bernhard, Sven

, p. 3099 - 3103 (2007/10/03)

Trioxo ester 15 was prepared by attachment of two vicinal C4 and C-6 ketide side chains on the anthraquinone core (6b). Mild base treatment of 15 initiated successive aldol condensations to produce the benzo[a]naphthacenequinone 16 regioselectively in one operation. Deprotection of 16 afforded the antibiotic G-2A (1) and decarboxylation of 1 lead to G-2N (2).
