Check Digit Verification of cas no
The CAS Registry Mumber 251998-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 251998-53:
(8*2)+(7*5)+(6*1)+(5*9)+(4*9)+(3*8)+(2*5)+(1*3)=175
175 % 10 = 5
So 251998-53-5 is a valid CAS Registry Number.

Enantiomeric synthesis of the SPIKET-P enantiomers
Sharma, Anubha,Iyer, Prema,Gamre, Sunita,Chattopadhyay, Subrata
, p. 1037 - 1040 (2004)
A convenient synthesis of the antipodes of the title compound has been developed starting from (R)-1,2,5,6-dicyclohexylidene mannitol. Some of the key features of the syntheses were simple reaction protocols, and stereoselective inversion of chiral 1,2-diol moiety via neighbouring group assisted acetylation.
Convergent synthesis of (+)-muconin

, p. 7827 - 7830 (2007/10/03)
An efficient total synthesis of the tetrahydropyran-bearing acetogenin muconin 1 is described. Palladium(0)-mediated crossed diyne coupling and the use of only D-glutamic acid as the origin of all absolute stereochemistry highlight this flexible approach that sets the stage for access to structural analogs for further study.
