141538-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141538-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,5,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141538-64:
(8*1)+(7*4)+(6*1)+(5*5)+(4*3)+(3*8)+(2*6)+(1*4)=119
119 % 10 = 9
So 141538-64-9 is a valid CAS Registry Number.

Stereospecific Synthesis of the Top-Half Precursor to the Antitumor Agent Vinblastine and a Simple Bisindole Analogue.
Magnus, Philip,Mendoza, Jose
, p. 899 - 902 (2007/10/02)
The stereospecific synthesis of a precursor to the top-half of vinblastine is described.Its non-oxidative coupling to m-methoxy-N,N-dimethylaniline provides access to the vinblastine analogue 18.
