Check Digit Verification of cas no

The CAS Registry Mumber 104505-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,0 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104505-81:
(8*1)+(7*0)+(6*4)+(5*5)+(4*0)+(3*5)+(2*8)+(1*1)=89
89 % 10 = 9
So 104505-81-9 is a valid CAS Registry Number.

The first total and biomimetic synthesis of violet-quinone (1), which has a dinaphthofuranquinone (DNFQ) framework, is described. This synthesis features the oxidative dimerization of 1-naphthol 4 and the construction of the DNFQ framework by photochemica

Dimeric Naphthoquinones, XIX.- Ammonium Cerium(IV) Nitrate as Oxidising Agent: Synthesis of Dimeric Naphthazarins

Laatsch, Hartmut

, p. 1669 - 1686 (2007/10/02)

Dimeric 1-naphthols (type 8 or 10) are easily oxidised using ammonium cerium(IV) nitrate, yielding the quinones of type 9 or 11.By dealkylation of the latter, several potentially naturally occuring binaphthazarin derivatives and the natural products 8'-hy
