736142-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 736142-11-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,6,1,4 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 736142-11:
(8*7)+(7*3)+(6*6)+(5*1)+(4*4)+(3*2)+(2*1)+(1*1)=143
143 % 10 = 3
So 736142-11-3 is a valid CAS Registry Number.

An enantioselective total synthesis of (-)-stemoamide
Sibi, Mukund P.,Subramanian, Thangaiah
, p. 1211 - 1214 (2007/10/03)
An enantioselective synthesis of (-)-stemoamide has been achieved in 14 steps starting from pyroglutamyl alcohol in ca. 7% overall yield. The key steps in the strategy are a conjugate addition of a vinyl copper reagent and a ring closing metathesis (RCM) reaction to form the seven-membered ring.
