894784-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 894784-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,4,7,8 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 894784-27:
(8*8)+(7*9)+(6*4)+(5*7)+(4*8)+(3*4)+(2*2)+(1*7)=241
241 % 10 = 1
So 894784-27-1 is a valid CAS Registry Number.

Total synthesis of 14β-fluorosteroids via a transannular Diels-Alder reaction
Beaubien, Sylvie,Deslongchamps, Pierre
, p. 29 - 48 (2007/10/03)
14β-Fluorosteroids 3 and 4 were synthesized to give a new class of unnatural cardenolides. The total synthesis of racemic 14β-fluorosteroids was accomplished using a highly diastereoselective transannular Diels-Alder reaction on a trans-cis-cis macrocycli
