259097-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 259097-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,0,9 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 259097-19:
(8*2)+(7*5)+(6*9)+(5*0)+(4*9)+(3*7)+(2*1)+(1*9)=173
173 % 10 = 3
So 259097-19-3 is a valid CAS Registry Number.

Oligonucleotides containing 7-deazaadenines: The influence of the 7- substituent chain length and charge on the duplex stability

Seela, Frank,Zulauf, Matthias

, p. 1878 - 1898 (2007/10/03)

Oligonucleotides carrying alkynyl and aminoalkynyl chains at the position 7 of 7-deazaadenine are synthesized, and the chain lengths as well as the bulkiness of the substituents are varied. The corresponding nucleosides 1a-f are prepared from 7-deaza-2'-d
