Check Digit Verification of cas no

The CAS Registry Mumber 873694-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,6,9 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 873694-56:
(8*8)+(7*7)+(6*3)+(5*6)+(4*9)+(3*4)+(2*5)+(1*6)=225

A novel versatile phosphoramidite building block for the synthesis of 5′- and 3′-hydrazide modified oligonucleotides

Antsypovich, Sergey I.,Von Kiedrowski, Guenter

, p. 211 - 226 (2007/10/03)

We introduce a novel versatile phosphoramidite building block for the modification of oligonucleotides (ONs) with acyl hydrazides on the 5′- or 3′-terminus, or both. The reaction of these hydrazide functionalized ONs with 4-methoxyphenylaldehyde is demons
