Check Digit Verification of cas no

The CAS Registry Mumber 20290-92-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,9 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20290-92:
(7*2)+(6*0)+(5*2)+(4*9)+(3*0)+(2*9)+(1*2)=80
80 % 10 = 0
So 20290-92-0 is a valid CAS Registry Number.

MODIFIED OLIGOMERIC COMPOUNDS AND USES THEREOF

-

Page/Page column 77-78; 84; 82-83; 136-137; 146-147; 149, (2021/02/19)

The present disclosure provides oligomeric compounds comprising a modified oligonucleotide having at least one stereo-non-standard nucleoside. An oligomeric compound comprising a modified oligonucleotide consisting of 12-30 linked nucleosides, wherein at least one nucleoside of the modified oligonucleotide is a stereo-non-standard nucleoside; and wherein the oligomeric compound is selected from among an RNAi compound, a modified CRISPR compound, and an artificial mRNA compound.

A procedure for facile synthesis of nucleosides using N, O-Bistrimethyl- silylacetamide in the presence of natural phosphate coated with potassium iodide

experimental part, p. 196 - 199 (2011/07/08)

Several α-D/L-arabino and β-D/L- xylonucleosides were synthesized in good yields under mild conditions by N-glycosylation of 1-O-acetyl D/L- arabino, and xylofuranose, with silylated nucleobases (uracil, thymine and 6- azauracil) in acetonitrile using natural phosphate (NP) coated with potassium iodide in BSA as catalyst.
