The CAS Registry Mumber 156159-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,5 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156159-82:
(8*1)+(7*5)+(6*6)+(5*1)+(4*5)+(3*9)+(2*8)+(1*2)=149
149 % 10 = 9
So 156159-82-9 is a valid CAS Registry Number.

The 2-Dansylethoxycarbonyl (=2-{[5-dimethylamino)naphthalen-1-yl]sulfonyl}ethoxycarbonyl; Dnseoc) group for protection of the 5'-hydroxy function in oligodeoxyribonucleotide synthesis

Bergmann,Pfleiderer

, p. 203 - 215 (2007/10/02)

Use of the 2-dansylethoxycarbonyl (=2-{[5-(dimethylamino)naphthalen-1-yl]sulfonyl])ethoxycarbonyl; Dnseoc) group as an intermediate 5'-OH protecting group in oligodeoxyribonucleotide synthesis using the automated phosphoramidite approach is described in a model study to an alternative strategy in RNA synthesis.
