Check Digit Verification of cas no

The CAS Registry Mumber 303142-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 303142-84:
(8*3)+(7*0)+(6*3)+(5*1)+(4*4)+(3*2)+(2*8)+(1*4)=89
89 % 10 = 9
So 303142-84-9 is a valid CAS Registry Number.

Novel stereoselective construction of a quaternary carbon: Application to synthesis of the cyclopentenedione moiety of madindolines

Hosokawa,Sekiguchi,Enemoto,Kobayashi

, p. 6429 - 6433 (2007/10/03)

Enantioselective synthesis of the cyclopentenedione moiety of madindolines was achieved. Stereoselective construction of a quaternary carbon was realized by alkylation of an enolate possessing chiral auxiliary. Cyclopentenedione was derived from a triketone precursor by intramolecular condensation. (C) 2000 Elsevier Science Ltd.
