109420-85-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109420-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109420-85:
(8*1)+(7*0)+(6*9)+(5*4)+(4*2)+(3*0)+(2*8)+(1*5)=111
111 % 10 = 1
So 109420-85-1 is a valid CAS Registry Number.

The 9-fluorenylmethoxycarbonyl (Fmoc) group and its use in oligonucleotide synthesis

Schirmeister-Tichy,Alvarado,Pfleiderer

, p. 1219 - 1220 (2007/10/03)

The introduction of the base-labile 9-fluorenylmethoxycarbonyl (Fmoc) group into the exocyclic amino function of 2'-deoxynucleosides and their dimethoxytritylation and phosphitylation is described. The resulting key intermediates were investigated in the

Synthesis of Oligonucleotides Containing Site-Specific Carcinogen Adducts. Preparation of the 2-Cyanoethyl N,N-Diisopropylphosphoramidite of N-(2'-Doexyguanosin-8-yl)-2-(acetylamino)fluorene with Fmoc as the Base-Protecting Group

Zhou, Yuanzhong,Chladek, Stanislav,Romano, Louis J.

, p. 556 - 563 (2007/10/02)

A 9-fluorenylmethoxycarbonyl (Fmoc) group was used to protect the exocyclic amine on the modified guanine of N-(2'-deoxyguanosin-8-yl)-2-(acetylamino)fluorene (dG-C8-AAF) so that oligonucleotides containing a site-specific AAF adduct could be prepared.Rea
