519-12-0 Usage
Description
An ergot alkaloid from the mycelia of Claviceps purpurea, the base yields colourless prisms when crystallized from Me2CO or MeOH. It is dextrorotatory having [α]20D + 165° (c 0.3, EtOH) or + 174° (c 1.0, CHCI3)' The ultraviolet spectrum in EtOH exhibits two absorption maxima at 243 and 313 mJ.1. The alkaloid forms crystalline salts with mineral acids, e.g. the hydrochloride, m.p. > 300°C and the nitrate, m.p. > 300°C;[α]20D + 190° (c 0.5,50% aqueous EtOH). The nitrogen atoms are present as an imino and a methylimino group.

Check Digit Verification of cas no
The CAS Registry Mumber 519-12-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 519-12:
(5*5)+(4*1)+(3*9)+(2*1)+(1*2)=60
60 % 10 = 0
So 519-12-0 is a valid CAS Registry Number.
