Check Digit Verification of cas no

The CAS Registry Mumber 252191-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,1,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 252191-99:
(8*2)+(7*5)+(6*2)+(5*1)+(4*9)+(3*1)+(2*9)+(1*9)=134
134 % 10 = 4
So 252191-99-4 is a valid CAS Registry Number.

Synthetic approaches to condensed aromatic analogues from etoposide. Synthesis of A-ring pyridazine picroetoposide

Meresse, Philippe,Bertounesque, Emmanuel,Imbert, Thierry,Monneret, Claude

, p. 12805 - 12818 (1999)

The studies feature the transformation of etoposide 1 into the pivotal intermediate (+)-19 for the elaboration of pyridazine-fused aromatic systems via a Stille cross-coupling. The synthesis of A-ring pyridazine picroetoposide (+)-21 has been achieved in
