Check Digit Verification of cas no
The CAS Registry Mumber 155520-94-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,2 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155520-94:
(8*1)+(7*5)+(6*5)+(5*5)+(4*2)+(3*0)+(2*9)+(1*4)=128
128 % 10 = 8
So 155520-94-8 is a valid CAS Registry Number.

A stereoselective synthesis of malbranicin
De L. Vanderlei, Jose Mauricio,Coelho, Fernando,Almeida, Wanda P.
, p. 2781 - 2785 (1997)
In this communication we describe the first synthesis of Malbranicin, a novel antibiotic quinone, isolated from Malbranchea cinnamomea. Our strategy was based on a diastereoselective alkylation of a chiral oxazolidinone enolate. Our results suggest the ab
