142428-26-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142428-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,2 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142428-26:
(8*1)+(7*4)+(6*2)+(5*4)+(4*2)+(3*8)+(2*2)+(1*6)=110
110 % 10 = 0
So 142428-26-0 is a valid CAS Registry Number.

New total synthesis of bikaverin
Bekaert, Alain,Andrieux, Jean,Plat, Michel
, p. 2805 - 2806 (1992)
On the basis of non-catalysed thermal condensation of a Mannich based with a phenol, followed by dehydration to an o.quinonic chromene further isomerized to a p.quinonic one, the synthesis of bikaverin 7 has been achieved via a six-step route involving selective dealkylation of bikaverin-dimethylether 6.
