68178-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68178-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,7 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68178-51:
(7*6)+(6*8)+(5*1)+(4*7)+(3*8)+(2*5)+(1*1)=158
158 % 10 = 8
So 68178-51-8 is a valid CAS Registry Number.

Anthracyclinones by Oxidative Dearomatization: Total Synthesis of SM-173B and Aranciamycinone

Kende, Andrew S.,Johnson, Stephen

, p. 727 - 729 (2007/10/02)

The aromatic naphthacenequinone 11 was converted by selective oxidative dearomatization of the A ring to enone 12 which was transformed into the aglycons SM-173B (4) and aranciamycinone (5).
