135131-55-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135131-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,3 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135131-55:
(8*1)+(7*3)+(6*5)+(5*1)+(4*3)+(3*1)+(2*5)+(1*5)=94
94 % 10 = 4
So 135131-55-4 is a valid CAS Registry Number.

The synthesis of oligodeoxynucleotides containing 4-thiothymidine residues

Nikiforov,Connolly

, p. 3851 - 3854 (1991)

Oligodeoxynucleotides containing 4-thiothymidine residues were obtained using the phosphoramidites of 2 and 3. Treatment with CH3COSK in EtOH was used to introduce the 4-thioketo function at the oligodeoxynucleotide level.

5′-O-(4-4′-dimethylthoxytrityl)-4-thiocyanatothymidine A useful intermediate for the preparation of various 4-substituted thymidine analogues

Nikiforov, Theo T.,Connolly, Bernard A.

, p. 2505 - 2508 (2007/10/02)

The thiocyanato group in 5′-O-(4,-4′-dimethoxytrityl)-4-thiocyanatothymidine 2 is easily displaced by a variety if O-, N=- and S-nucleophiles, making this compound a useful intermediate for the preparation of 4-substituted thymidine analogues.
