439292-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439292-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,2,9 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 439292-97:
(8*4)+(7*3)+(6*9)+(5*2)+(4*9)+(3*2)+(2*9)+(1*7)=184
184 % 10 = 4
So 439292-97-4 is a valid CAS Registry Number.

Synthetic route to the GE3 cyclodepsipeptide.
Hale, Karl J,Lazarides, Linos
, p. 1903 - 1906 (2007/10/03)
[reaction: see text] A reasonably efficient [2 + 2 + 2] fragment condensation strategy has been developed for assembling the cyclodepsipeptide sector of GE3 that involves 5-7. A Carpino HATU-mediated macrolactamization was used to close the 19-membered cy
