130887-31-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130887-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,8 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130887-31:
(8*1)+(7*3)+(6*0)+(5*8)+(4*8)+(3*7)+(2*3)+(1*1)=129
129 % 10 = 9
So 130887-31-9 is a valid CAS Registry Number.

An efficient approach to the synthesis of thymidine derivatives containing phosphate-isosteric methylene acetal linkages

Veeneman,Van Der Marel,Van Den Elst,Van Boom

, p. 1547 - 1562 (2007/12/18)

Iodonium ion promoted condensation of properly protected 3′-O-methylthiomethyl or 3′-O-(4-penten-1-oxymethyl)-thymidine with 3′-O-methoxyacetyl-thymidine, was explored. A judicious choice of the iodoinium source and protecting groups led to an efficient preparation of thymidine dimers having internucleosidic-3′5′)-methylene bonds. The latter procedure was utilized towards the synthesis, in solution and on a solid support, of DNA-fragments containing one or more T-CII2-T dimers. Further, 5′-O-methylthiomethyl-3′-O-methoxyacetyl-N 3-benzoyl-thymidine proved to be a suitable donor for the introduction of 5′-O-methylene acetal-linkage s between 2,3,4,6-tetra-Obenzyl-D-glucose, benzyl N-benzyloxycarbonyl-L-serine and dibenzyl phosphate.
