Uses
Used in Agricultural Industry:
Spinosyn D 17-pseudoaglycone is used as a weak insecticide for controlling certain pests. However, its activity is significantly reduced compared to its parent compound, spinosyn D, making it less effective against insects like tobacco budworms (H. virescens) at concentrations up to 64 ppm.
Used in Research and Development:
Spinosyn D 17-pseudoaglycone serves as a valuable compound for research purposes, particularly in understanding the structure-activity relationship of spinosyns and their derivatives. It can be used to study the importance of the forosamine moiety in the insecticidal activity of spinosyns and to develop new strategies for improving the potency of these compounds.
Used in Environmental Studies:
As a degradation product of spinosyn D, spinosyn D 17-pseudoaglycone can be used in environmental studies to assess the levels of this compound in animals and the environment. This information can help in understanding the environmental impact of spinosyns and their degradation products, as well as in developing strategies for minimizing their ecological footprint.
Used in Animal Health Products:
Spinosyn D 17-pseudoaglycone, along with other spinosyns, has been explored for their potential use in animal health products. Although its insecticidal activity is weak, it may still have some applications in controlling pests in the animal health industry, where its reduced potency could be an advantage in minimizing the risk of resistance development.
Check Digit Verification of cas no
The CAS Registry Mumber 131929-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,2 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131929-55:
(8*1)+(7*3)+(6*1)+(5*9)+(4*2)+(3*9)+(2*5)+(1*5)=130
130 % 10 = 0
So 131929-55-0 is a valid CAS Registry Number.

Conversion of spinosyn A and spinosyn D to their respective 9- and 17-pseudoaglycones and their aglycones
Creemer, Lawrence C.,Kirst, Herbert A.,Paschal, Jonathan W.
, p. 795 - 800 (1998)
Forosamine at the 17-position of spinosyns A and D was hydrolyzed under mild acidic conditions to give the corresponding 17-pseudoaglycones. The tri-O-methylrhamnose at the 9-position of the 17-pseudoaglycone of spinosyn A was hydrolyzed under more vigorous acidic conditions to give the aglycone of spinosyn A. However, these conditions led to decomposition of the 17-pseudoaglycone of spinosyn D, presumably due to more facile protonation of the 5,6-double bond to produce a tertiary carbonium ion which undergoes further rearrangements. Spinosyns J and L (3'-O-demethyl spinosyn A and D, respectively) obtained from fermentation of biosynthetically-blocked mutant strains of Saccharopolyspora spinosa, were oxidized to give the corresponding 3'-keto-derivatives and the resultant keto-sugars were then β-eliminated under basic conditions to give the 9-pseudoaglycones of spinosyns A and D respectively. Forosamine at the 17-position of the 9-pseudoaglycone of spinosyn D was then readily hydrolyzed to yield the aglycone of spinosyn D.
