845306-87-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 845306-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,3,0 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 845306-87:
(8*8)+(7*4)+(6*5)+(5*3)+(4*0)+(3*6)+(2*8)+(1*7)=178
178 % 10 = 8
So 845306-87-8 is a valid CAS Registry Number.

Synthesis of mixed sequence borane phosphonate DNA

McCuen, Heather Brummel,Noe, Mary S.,Sierzchala, Agnieszka B.,Higson, Adrian P.,Caruthers, Marvin H.

, p. 8138 - 8139 (2006)

A novel solid-phase phosphoramidite-based method has been developed for the synthesis of borane phosphonate DNA. Keys to this new approach are replacement of the common 5′-dimethoxytrityl blocking group with a 5′-silyl ether and the use of new protecting

Synthesis and biological activity of borane phosphonate DNA

Olesiak, Magdalena,Krivenko, Angelika,Krishna, Heera,Caruthers, Marvin H.

experimental part, p. 921 - 932 (2011/06/24)

Borane phosphonate oligodeoxyribonucleotides are synthesized from 5'-O-[benzhy droxybis(trimethylsilyloxy)silyl]-2'-deoxyribonucleoside-3'-O- methylphosphoramidites. The exocyclic amine functions of adenine, guanine, and cytosine are protected with trimet

Synthesis and biochemical activity of new oligonucleotide analogs

McCuen, Heather Brummel,Noe, Mary S.,Olesiak, Magdalena,Sierzchala, Agnieszka B.,Caruthers, Marvin H.,Higson, Adrian P.

experimental part, p. 349 - 363 (2009/04/07)

Borane phosphonate deoxyoligonucleotides are synthesized from 5′-O-benzhydroxybis(trimethylsilyloxy)silyl-2′-deoxynucleoside- 3′-phosphoramidites. The exocyclic amines of adenine and cytosine are protected with dimethoxytrityl and trimethoxytrityl, respec
