88643-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88643-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,6,4 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88643-05:
(7*8)+(6*8)+(5*6)+(4*4)+(3*3)+(2*0)+(1*5)=164
164 % 10 = 4
So 88643-05-4 is a valid CAS Registry Number.

Synthesis of (-)-Malyngolide
Floerke, Holger,Schaumann, Ernst
, p. 147 - 152 (2007/10/03)
δ-Lactone (-)-malyngolide (1) was synthesized by starting from the optically active epoxide 5.Coupling of derivative 3 with propargyl anion 11 and subsequent metal-catalyzed methylation of the triple bond provided 14 incorporating all the carbon atoms of
