853061-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853061-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,0,6 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 853061-26:
(8*8)+(7*5)+(6*3)+(5*0)+(4*6)+(3*1)+(2*2)+(1*6)=154
154 % 10 = 4
So 853061-26-4 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
