401906-49-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 401906-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,1,9,0 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 401906-49:
(8*4)+(7*0)+(6*1)+(5*9)+(4*0)+(3*6)+(2*4)+(1*9)=118
118 % 10 = 8
So 401906-49-8 is a valid CAS Registry Number.

Synthesis of D-Altritol Nucleosides with a 3′ -O-Tert-Butyldimethylsilyl Protecting Group

Abramov, Michael,Marchand, Arnaud,Calleja-Marchand, Agnes,Herdewijn, Piet

, p. 439 - 455 (2004)

Four D-altritol nucleosides with a 3′-O-tert- butyldimethylsilyl protecting group are synthesized (base moieties are adenine, guanine, thymine and 5-methylcytosine). The nucleosides are obtained by ring opening reaction of 1,5:2,3-dianhydro-4,6-O-benzylid

TETRAHYDROPYRAN NUCLEIC ACID ANALOGS

-

Page/Page column 50-51, (2010/08/18)

The present disclosure describes tetrahydropyran nucleoside analogs, oligomeric compounds prepared therefrom and methods of using the oligomeric compounds. More particularly, novel tetrahydropyran nucleoside analogs are provided having at least one chiral substituent that are expected to be useful for enhancing one or more properties of oligomeric compounds such as nuclease resistance and/or binding affinity. In certain embodiments, the oligomeric compounds are expected to hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
