885674-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 885674-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,6,7 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 885674-91:
(8*8)+(7*8)+(6*5)+(5*6)+(4*7)+(3*4)+(2*9)+(1*1)=239
239 % 10 = 9
So 885674-91-9 is a valid CAS Registry Number.

Niess, Barbara,Hartung, Ingo V.,Haustedt, Lars O.,Hoffmann, H. Martin R.
, p. 1132 - 1143 (2007/10/03)
The synthesis of a protected 9,9′,10,10′-tetradehydro- disorazole C1 is described. A C1-C8 oxazole fragment with an E-vinylic iodide terminus is coupled to a suitable C9-C19 enyne. The resulting ω-hydroxycarboxylic acid is cyclodimerized stepwi
