561-07-9 Usage
Purification Methods
It crystallises from EtOH with 198-200o uncorrected (187.5-188.5o) and from Et2O or Me2CO. Its solubility at ~25o in EtOH, CHCl3 and Et2O is 4%, 5% and 10% respectively. In c 1, EtOH, it has [] 20 +22o changing to +19o in 4 hours. [Markwood J Am Chem Soc 16 931 1927.] The hydrochloride has m 214o(dec) from MeOH or MeOH/Et2O. [Weissner et al. Can J Chem 50 1925 1972, Jacobs & Craig J Biol Chem 127 363 1939, Beilstein 21 III/IV 2867.]
Check Digit Verification of cas no
The CAS Registry Mumber 561-07-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 561-07:
(5*5)+(4*6)+(3*1)+(2*0)+(1*7)=59
59 % 10 = 9
So 561-07-9 is a valid CAS Registry Number.

DELSTAPHIGINE AND 14-O-BENZOYLDELPHONINE, NEW ALKALOIDS FROM DELPHINIUM STAPHISAGRIA LINNE
Pelletier, S. William,Ross, Samir A.,Etse, Joseph T.
, p. 2467 - 2474 (2007/10/02)
Delstaphigine (1) and 14-O-benzoyldelphonine (2), two new C19-diterpenoid alkaloids, and chasmaconitine (4) have been isolated from the seeds of Delphinium staphisagria.The structures of these alkaloids were determined from spectral data and by correlation with alkaloids of established structures.Thus methylation of delstaphigine (1) afforded delphinine (3). 14-O-Benzoyldelphonine (2) was synthesized from both delphinine (3) and delphonine (5).Chasmaconitine (4) has not been previously isolated from a Delphinium species.
