13588-16-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13588-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,8 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13588-16:
(7*1)+(6*3)+(5*5)+(4*8)+(3*8)+(2*1)+(1*6)=114
114 % 10 = 4
So 13588-16-4 is a valid CAS Registry Number.

USPALLATINE, A PYRROLIZIDINE ALKALOID FROM SENECIO USPALLATENSIS

Pestchanker, M. J.,Ascheri, M. S.,Giordano, O. S.

, p. 1622 - 1624 (1985)

A new pyrrolizidine alkaloid uspallatine was isolated from roots of Senecio uspallatensis together with the previously known retrorsine.The structure of the new alkaloid was established by spectroscopical data and chemical transformation.Key Word Index - Senecio uspallatensis; Compositae; pyrrolizidine alkaloids; uspallatine.

Pyrrolizidine Alkaloid Biosynthesis. Synthesis of 3H-Labelled Trachelanthamidine and Isoretronecanol and their Incorporation into Three Pyrrolizidine Bases (Necines)

Kunec, Ellen K.,Robins, David J.

, p. 1437 - 1441 (2007/10/02)

(+/-)-Isoretronecanol (22) and (+/-)-trachelanthamidine (24) were prepared by 1,3-dipolar cycloaddition of N-formylproline with ethyl propiolate followed by reduction steps.These 3H-labelled 1-hydroxymethylpyrrolizidines together with putrescine were fed to Senecio isatideus which produces retrorsine (1); S. pleistocephalus which yields rosmarinine (8); and Cynoglossum officinale which affords echinatine (5).The double labelling experiments demonstrated that isoretronecanol is incorporated much more efficiently into rosmarinine than into retrorsine or echinatine, whereas trachelanthamidine is a much more efficient precursor for retrorsine and echinatine.Base hydrolysis of retrorsine and echinatine labelled with trachelanthamidine and of rosmarinine labelled with isoretronecanol established that most of the 3H-label was in the base portions, retronecine (2), heliotridine (6), and rosmarinecine (9), respectively.Further degradation of retronecine and rosmarinecine showed that most of the radioactivity was confined to the β-alanine (4) portion.The biosynthetic pathways to isoretronecanol and trachelanthamidine apparently diverge prior to the formation of these 1-hydroxymethylpyrrolizidines, probably during the cyclisation of an immonium ion (14) to form the 1-formylpyrrolizidines (15) and (17).

STEREOSELECTIVE SYNTHESIS OF (+/-)-INTEGERRINECIC ACID

Narasaka, Koichi,Uchimaru, Tadafumi

, p. 57 - 58 (2007/10/02)

A synthesis of (+/-)-integerrinecic acid, an acid part of 12-membered bislactonic pyrrolizidine alkaloid, has been achieved stereoselectively starting from 2-methyl-2-cyclopentanone.
