75291-15-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75291-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,9 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75291-15:
(7*7)+(6*5)+(5*2)+(4*9)+(3*1)+(2*1)+(1*5)=135
135 % 10 = 5
So 75291-15-5 is a valid CAS Registry Number.

Diastereoselective zinc-catalyzed conjugate addition of alkynes
Knoepfel, Thomas F.,Boyall, Dean,Carreira, Erick M.
, p. 2281 - 2283 (2007/10/03)
The conjugate addition of in situ generated zinc alkynylides is reported. The use of chiral, ephedrine derived acceptors provides access to enantiomerically enriched β-alkynyl acids in good yields.
