Check Digit Verification of cas no
The CAS Registry Mumber 128948-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,4 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128948-11:
(8*1)+(7*2)+(6*8)+(5*9)+(4*4)+(3*8)+(2*1)+(1*1)=158
158 % 10 = 8
So 128948-11-8 is a valid CAS Registry Number.

PROSTANOIDS. XXXII. SYNTHESIS OF (+)-PROSTAGLANDIN F2α
Miftakhov, M. S.,Adler, M. E.,Komissarova, N. G.,Tolstikov, G. A.
, p. 1274 - 1280 (2007/10/02)
Natural prostaglandin F2α was obtained from cyclopentadiene monoxide.The key stages of the synthesis included the following: Optical resolution of (+/-)-trans-2-carboxymethylcyclopent-3-en-1-ol with the transformation of its (-)-enantiomer into (-)-cis-2-oxabicyclooct-6-en-3-one and then into (-)-7α-triethylsilyloxy-6β-triethylsilyloxymethyl-cis-2-oxabicyclooctan-3-one; selective oxidation of the latter by the DMSO-(COCl)2 system; condensation of the intermediate (-)-7α-triethylsilyloxy-6β-formyl-cis-2-oxabicyclooctan-3-one with dimethyl 2-oxoheptylphosphonate under the conditions of phase-transfer catalysis with the production of (-)-7α-hydroxy-6β-(3-oxo-1E-octenyl)-cis-2-oxabicyclooctan-3-one; conversion of the latter into (+)-PGF2α by standard methods.
