28421-57-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28421-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,2 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28421-57:
(7*2)+(6*8)+(5*4)+(4*2)+(3*1)+(2*5)+(1*7)=110
110 % 10 = 0
So 28421-57-0 is a valid CAS Registry Number.

A CONVENIENT SYNTHESIS OF 1α,25-DIHYDROXY-28-NORVITAMIN-D2

Moriarty, Robert M.,Kim, Joonggon,Penmasta, Raju

, p. 3741 - 3744 (1992)

The title compound was synthesized via the Julia olefination using ring B-diene protected 3β-hydroxy-23,24-bisnorchola-5,7-diene-22-al acetate and the side-chain synthon 2-methyl-4-phenylsulfonyl-2-(tetrahydropyranyloxy)butane.Ring B-deprotection, photoly

New Intermediates in Synthesis of Provitamins D

Litvinovskaya,Koval',Khripach

, p. 1442 - 1446 (2007/10/03)

The first synthesis of provitamins possessing isoxazole ring in the side chain is described. The synthesis is performed from ergosterol acetate via steroid C22-nitrile oxide by means of 1,3-dipolar cycloaddition of the latter to low-molecular a

STARFISH SAPONINS VI - UNIQUE 22,23-EPOXISTEROIDAL CYCLIC GLYCOSIDES, MINOR CONSTITUENTS FROM ECHINASTER SEPOSITUS

Riccio, R.,Simone, E. De,Dini, A.,Minale, L.,Pizza, C.,et al.

, p. 1557 - 1560 (2007/10/02)

On the basis of comparative 1H- and 13C-n.m.r. data, the structures of the minor saponins from the starfish Echinaster sepositus have been elucidated to be 2-4.They closely resemble 1, the major saponin from the same starfish, and, in addition to the cyclic trisaccharide moiety bridging C-3 and C-6 of the steroid, include epoxide functionalities in the steroidal side-chains.
