66556-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66556-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,5 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66556-52:
(7*6)+(6*6)+(5*5)+(4*5)+(3*6)+(2*5)+(1*2)=153
153 % 10 = 3
So 66556-52-3 is a valid CAS Registry Number.

Total Synthesis of dl-Bisnorvernolepin
Kieczykowszi, G. R.,Quesada, Martha L.,Schlessinger, R. H.
, p. 782 - 790 (2007/10/02)
A 19-step total synthesis of the racemic form of bisnorvernolepin, 4, has been achieved starting from ethyl crotonate.The synthesis is both regiospecific and stereospecific in that it leads to the exclusive formulation of bisnorvernolepin without concomin
