664982-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 664982-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,9,8 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 664982-44:
(8*6)+(7*6)+(6*4)+(5*9)+(4*8)+(3*2)+(2*4)+(1*4)=209
209 % 10 = 9
So 664982-44-9 is a valid CAS Registry Number.

Synthesis of the Putative Structure of Eupomatilone-6
Gurjar, Mukund K.,Cherian, Joseph,Ramana
, p. 317 - 319 (2007/10/03)
(Matrix presented) The synthesis of eupomatilone-6 (1) has been achieved by using Suzuki coupling, Sharpless asymmetric dihydroxylation, and intramolecular Horner-Wadsworth-Emmons reactions. The spectroscopic studies carried out on synthetic eupomatilone-
