552308-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 552308-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,3,0 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 552308-06:
(8*5)+(7*5)+(6*2)+(5*3)+(4*0)+(3*8)+(2*0)+(1*6)=132
132 % 10 = 2
So 552308-06-2 is a valid CAS Registry Number.

Synthesis and incorporation into PNA of fluorinated olefinic PNA (F-OPA) monomers.
Hollenstein, Marcel,Leumann, Christian J
, p. 1987 - 1990 (2007/10/03)
[structure: see text] A fluorinated OPA monomer containing the base thymine ((Z)-t-F-OPA) was synthesized in 12 steps, featuring a highly selective allylic over homoallylic Mitsunobu substitution for the introduction of the nucleobase. F-OPA modified PNA
