Check Digit Verification of cas no

The CAS Registry Mumber 2275-26-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,7 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2275-26:
(6*2)+(5*2)+(4*7)+(3*5)+(2*2)+(1*6)=75
75 % 10 = 5
So 2275-26-5 is a valid CAS Registry Number.

Rearrangements of α-Diazo-β-hydroxyketones for the Synthesis of Bicyclo[m.n.1]alkanones

Li, Zhengning,Lam, Shuk Mei,Ip, Ignatius,Wong, Wing-Tak,Chiu, Pauline

supporting information, p. 4464 - 4467 (2017/09/11)

Rhodium-catalyzed decomposition of fused bicyclic α-diazo-β-hydroxyketones results in good yields of bridged bicyclo[m.n.1]ketones via a rearrangement pathway.

Construction of fused cyclooctanoid ring systems via seven-membered ring carbonyl ylides

Muthusamy, Sengodagounder,Babu, Srinivasarao Arulananda,Gunanathan, Chidambaram,Suresh, Eringathodi,Dastidar, Parthasarathi

, p. 801 - 811 (2007/10/03)

A series of α-diazo carbonyl compounds tethered to cyclopentanone/cyclohexanone/1-tetralone units have been synthesized using a diazomethane solution to construct various fused cyclooctane ring systems via rhodium-generated carbonyl ylides. The reaction of rhodium(II) acetate dimer with various α-diazo carbonyl compounds generated transient cyclic seven-membered ring carbonyl ylides, which underwent facile 1,3-dipolar cycloadditions with dipolarophiles, like N-phenylmaleimide, p-benzoquinone, and DMAD to furnish a variety of fused epoxy-bridged cyclooctane ring systems in a tandem manner. Interestingly, an oxepine ring system was generated via an intramolecular proton transfer of a seven-membered ring carbonyl ylide. A tri-oxa polycyclic compound was obtained in the case of p-benzoquinone as dipolarophile. A single-crystal X-ray analysis of a fused cyclootanoid derivative is reported to decisively establish the structure and stereochemistry of the fused epoxy-bridged cyclooctane ring systems; a further analysis revealed the existence of a unique intermolecular C-H ···π interaction motif in the solid-state architecture.

Ring-D aromatic phytosteroids; a model for biogenesis by way of carbon radical rearrangement

Green, Stuart P.,Whiting, Donald A.

, p. 1027 - 1034 (2007/10/03)

A mechanism is postulated for the biogenesis of the unique ring-D aromatic phytosteroids from Nicandra physaloides, which involves rearrangement, ring expansion, and aromatisation of a carbon radical generated by cytochrome P450 (Scheme 1). In support, model hydrindene acids 15b and 18b have been synthesized and subjected to homolytic decarboxylation; the latter acid yielded 6-methyltetralin 24, in biomimetic fashion. The isomeric acid afforded not only 6-methyltetralin 24 but also 5-methyltetralin 26; mechanisms for this unusual rearrangement are discussed.
