Check Digit Verification of cas no

The CAS Registry Mumber 259886-51-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,8,8 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 259886-51:
(8*2)+(7*5)+(6*9)+(5*8)+(4*8)+(3*6)+(2*5)+(1*1)=206
206 % 10 = 6
So 259886-51-6 is a valid CAS Registry Number.

SERS multiplexing of methylxanthine drug isomersviahost-guest size matching and machine learning

Chio, Weng-I Katherine,Dinish, U. S.,Jones, Tabitha,Lee, Tung-Chun,Liu, Jia,Olivo, Malini,Parkin, Ivan P.,Perumal, Jayakumar

supporting information, p. 12624 - 12632 (2021/10/06)

Multiplexed detection and quantification of structurally similar drug molecules, methylxanthine MeX, incl. theobromine TBR, theophylline TPH and caffeine CAF, have been demonstratedviasolution-based surface-enhanced Raman spectroscopy (SERS), achieving highly reproducible SERS signals with detection limits down to ~50 nM for TBR and TPH, and ~1 μM for CAF. Our SERS substrates are formed by aqueous self-assembly of gold nanoparticles (Au NPs) and supramolecular host molecules, cucurbit[n]urils (CBn,n= 7, 8). We demonstrate that the binding constants can be significantly increased using a host-guest size matching approach, which enables effective enrichment of analyte molecules in close proximity to the plasmonic hotspots. The dynamic range and the robustness of the sensing scheme can be extended using machine learning algorithms, which shows promise for potential applications in therapeutic drug monitoring, food processing, forensics and veterinary science.

Cucurbit[n]uril formation proceeds by step-growth cyclo-oligomerization

Huang, Wei-Hao,Zavalij, Peter Y.,Isaacs, Lyle

supporting information; scheme or table, p. 8446 - 8454 (2009/02/02)

In contrast to the high yield formation of cucurbit[n]uril (CB[n]) from a 1:2 ratio of glycoluril to formaldehyde, the condensation of glycoluril with less than 2 equiv of formaldehyde delivers a reaction mixture that contains glycoluril oligomers (2-6) and CB[n] compounds that lack one or more methylene bridges known as nor-seco-cucurbit[n]urils (ns-CB[n]). In this paper we report the chromatographic purification of C-shaped glycoluril oligomers (dimer-hexamer), their characterization in solution, and their X-ray crystal structures. Quite interestingly, despite being acyclic glycoluril pentamer 5 and hexamer 6 retain the ability to bind to guests typical of CB[6] but are also able to expand their cavity to accommodate larger guests like cationic adamantane derivatives. We performed product resubmission experiments with glycoluril oligomers 2-6 and found preferences for the formation of specific ring sizes during CB[n] formation. A comprehensive mechanistic scheme is proposed that accounts for the observed formation of 2-6 and ns-CB[n]. Overall, the experiments establish that a step-growth cyclo-oligomerization process operates during CB[n] formation.
