253787-80-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 253787-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,7,8 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 253787-80:
(8*2)+(7*5)+(6*3)+(5*7)+(4*8)+(3*7)+(2*8)+(1*0)=173
173 % 10 = 3
So 253787-80-3 is a valid CAS Registry Number.

A concise route to D-erythro-sphingosine from N-Boc-L-serine derivatives via sulfoxide or sulfone intermediates

Chun, Jiong,Li, Guoqing,Byun, Hoe-Sup,Bittman, Robert

, p. 375 - 377 (2007/10/03)

Sulfoxide and sulfone intermediates 7 and 15, respectively, were employed to synthesize synthons 3 and 4, which are readily converted to the naturally occurring (2S,3R,4(E))-sphingosine 1 and (2S,3R)-sphinganine 2.

Phytosphingosines - A facile synthesis and spectroscopic protocol for configurational assignment

Shirota, Osamu,Nakanishi, Koji,Berova, Nina

, p. 13643 - 13658 (2007/10/03)

A facile synthesis of four of the eight configurational isomers of phytosphingosine has been performed by employing Wittig and Julia olefination followed by Sharpless dihydroxylation. The set of these four stereoisomers served as model compounds for developing general chemical/CD/NMR protocols for assigning relative and absolute configurations of all phytosphingosine isomers. The procedure is based on a two-step derivatization to 2-N- naphthimide-1,3,4-0-trinaphthoate derivatives which gives rise to unique exciton coupled circular dichroic and 'H-NMR spectra in selected solvents. The spectra can be used as reference data for assignment of relative as well as absolute configurations of phytosphingosine isomers and congeners at the low-nanomole level.
