137576-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137576-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,7 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137576-43:
(8*1)+(7*3)+(6*7)+(5*5)+(4*7)+(3*6)+(2*4)+(1*3)=153
153 % 10 = 3
So 137576-43-3 is a valid CAS Registry Number.

Synthesis of an ecdysteroid inhibitor of ecdysone biosynthesis
Mauvais, Antony,Hetru, Charles,Luu, Bang
, p. 5171 - 5174 (2007/10/02)
The hydroboration-oxidation of a Δ5,7 pregnadiene leads to a Δ76α-hydroxyderivative. This is converted to an acetylenic analogue of ecdysteroids, which is an inhibitor of their biosynthesis in vitro.
