Check Digit Verification of cas no

The CAS Registry Mumber 1311298-63-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,1,2,9 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1311298-63:
(9*1)+(8*3)+(7*1)+(6*1)+(5*2)+(4*9)+(3*8)+(2*6)+(1*3)=131
131 % 10 = 1
So 1311298-63-1 is a valid CAS Registry Number.

AROMATIC COMPOUND, MODIFICATION CARRIER THAT USES SAME AND IS USED FOR SYNTHESIZING AN OLIGONUCLEOTIDE DERIVATIVE, OLIGONUCLEOTIDE DERIVATIVE, AND OLIGONUCLEOTIDE CONSTRUCT

-

, (2012/11/06)

The present invention provides an oligonucleotide derivative that enables to easily synthesize an oligonucleotide derivative chemically modified at the 3'-end with two moieties each having a benzene or pyridine structure with a few steps, an aromatic compound serving as a precursor for preparing the modification carrier for synthesizing oligonucleotide derivative, and the oligonucleotide derivative and the oligonucleotide construct using the same, that is chemically modified at the 3'-end with two moieties each having a benzene or pyridine structure, and has good permeability through a cell membrane and excellent nuclease resistance. The modification carrier for synthesizing oligonucleotide derivative, comprising a unit and a carrier carrying the unit directly or via a linker, wherein the unit is represented by the formula (a): wherein, R1 to R6 each independently represent hydrogen or a substituent other than hydrogen; Z1 and Z2 each independently represent CH or nitrogen; and X represents oxygen or sulfur.
