Check Digit Verification of cas no

The CAS Registry Mumber 195821-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,8,2 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 195821-68:
(8*1)+(7*9)+(6*5)+(5*8)+(4*2)+(3*1)+(2*6)+(1*8)=172
172 % 10 = 2
So 195821-68-2 is a valid CAS Registry Number.

Nucleotides (Part LXIX): Synthesis of phosphoramidite building blocks of isoxanthopterin n8-(2'-deoxy-β-dribonucleosides): New fluorescence markers for oligonucleotide synthesis

Lehbauer, Joerg,Pfleiderer, Wolfgang

, p. 2330 - 2342 (2007/10/03)

The chemical synthesis of isoxanthopterin and 6-phenylisoxanthopterin N8-(2'-deoxy-βD-ribofuranosyl nucleosides) is described as well as their conversion into suitably protected 3'-phosphoramidite building blocks to be used as marker molecules for DNA synthesis. Applying the npe/inpeoc (=2-(4-nitrophenyl)ethyl'[2-(4-nitrophenyl)ethoxy]carbonyl) strategy, we used the new building blocks in the preparation of oligonucleotides by an automated solid-support approach. The hybridization properties of a series of labelled oligomers were studied by UV-melting techniques. It was found that the newly synthesized markers only slightly interfered with the abilities of the labelled oligomers to form stable duplexes with complementary oligonucleotides.
