Poison by
intraperitoneal and intravenous routes.
Experimental teratogenic and reproductive
effects. Human systemic effects by
ingestion: ddation of the arteries or veins.

Check Digit Verification of cas no
The CAS Registry Mumber 478-84-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 478-84:
(5*4)+(4*7)+(3*8)+(2*8)+(1*4)=92
92 % 10 = 2
So 478-84-2 is a valid CAS Registry Number.

Process for brominating ergot alkaloids
-
, (2008/06/13)
The present invention provides an improved process for the production of a compound of formula I STR1 wherein R1 is carboxyl, alkoxy(C1-5)carbonyl, amido, alkyl(C1-5)amido, di(alkyl(C1-5)amido or an amido radical of formula II STR2 wherein Ra is alkyl(C1-4), Rb is alkyl(C1-4) or benzyl, and R2 is hydrogen or alkyl(C1-4), and either R3 is hydrogen and R4 is hydrogen or alkoxy(C1-4) or R3 and R4 together are a single bond, characterized in that a compound of formula III STR3 wherein R1 to R4 are as defined above, is brominated with a bromine complex of 3-bromo-6-chloro-2-methyl-imidazo[1,2-b]pyridazine.
