898534-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 898534-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,5,3 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 898534-13:
(8*8)+(7*9)+(6*8)+(5*5)+(4*3)+(3*4)+(2*1)+(1*3)=229
229 % 10 = 9
So 898534-13-9 is a valid CAS Registry Number.

Convergent synthesis of the quinolone substructure of BILN 2061 via carbonylative sonogashira coupling/cyclization
Haddad, Nizar,Tan, Jonathan,Farina, Vittorio
, p. 5031 - 5034 (2006)
A convergent synthesis of quinolone 2 (key substructure of the protease inhibitor BILN 2061) was developed via palladium-catalyzed carbonylation of 2-iodo-5-methoxy-aniline (4) with thiazolylacetylene 5.
