4251-20-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4251-20-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4251-20:
(6*4)+(5*2)+(4*5)+(3*1)+(2*2)+(1*0)=61
61 % 10 = 1
So 4251-20-1 is a valid CAS Registry Number.

Synthesis and UV photolysis of oligodeoxynucleotides that contain 5-(phenylthiomethyl)-2'-deoxyuridine: a specific photolabile precursor of 5-(2'-deoxyuridilyl)methyl radical.

Romieu,Bellon,Gasparutto,Cadet

, p. 1085 - 1088 (2007/10/03)

[formula: see text] The title exocyclic radical (2) is generated via photochemical cleavage of 5-(phenylthiomethyl)-2'-deoxyuridine (8). The latter thionucleoside (8) was successfully incorporated into DNA oligomers by automated DNA synthesis using phosphoramidite chemistry. UV exposure of 8 containing oligonucleotides under (an)aerobic conditions gives rise to specific base lesions. The photoproducts have been isolated and further characterized on the basis of detailed NMR and mass spectrometric analyses.
