65195-51-9 Usage
Uses
Used in Agricultural Industry:
Avermectin-A1a is used as a pesticide for controlling various insect pests. Its application helps in reducing the damage caused by these pests to crops, thereby increasing agricultural productivity and crop yield.
Used in Medical Industry:
Avermectin-A1a is used as an anthelmintic drug for treating parasitic worm infections. It is particularly effective against a range of parasitic worms, including roundworms, whipworms, and filarial worms, which can cause severe health issues in humans and animals. By targeting these parasites, Avermectin-A1a contributes to improved health and well-being for those affected by these infections.
Check Digit Verification of cas no
The CAS Registry Mumber 65195-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,9 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65195-51:
(7*6)+(6*5)+(5*1)+(4*9)+(3*5)+(2*5)+(1*1)=139
139 % 10 = 9
So 65195-51-9 is a valid CAS Registry Number.

SYNTHESIS OF 19-EPI-AVERMECTIN A1a FROM AVERMECTIN B1a
Hanessian, Stephen,Chemla, Philippe
, p. 2719 - 2722 (2007/10/02)
The conversion of avermectin B1a into 19-epi-avermectin A1a was accomplished by an intramolecular Mitsunobu reaction of a Δ2-conjugated seco acid with inversion of configuration, followed by a stereocontrolled deconjugation.

Key fragments for the total synthesis of the title compound were elaborated from D-ribose and D-glucose and coupled through a crossed aldol dehydration maneuver (33 + 44→46). An intramolecular variant of the Nozaki reaction (47→48) led to the all-critical
