Check Digit Verification of cas no

The CAS Registry Mumber 1129407-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,4,0 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1129407-45:
(9*1)+(8*1)+(7*2)+(6*9)+(5*4)+(4*0)+(3*7)+(2*4)+(1*5)=139
139 % 10 = 9
So 1129407-45-9 is a valid CAS Registry Number.

Synthesis of amphidinolide e C10-C26 fragment

Esteban, Jorge,Costa, Anna M.,Vilarrasa, Jaume

experimental part, p. 4843 - 4846 (2009/05/31)

(Equation Presented) The key C10-C26 fragment in a total synthesis of (-)-amphidinolide E has been prepared from an oxolane-containing C10-C17 segment (9, derived from L-glutamic acid) via a Julia-Kocienski reaction with aldehyde 3, followed by a Sharpless AD to obtain the desired diol. The C22-C26 fragment was installed by means of an efficient Suzuki-Molander coupling, with an organotrifluoroborate reagent (4, arising from a cross-metathesis reaction between a vinylboronate and 2-methyl-1,4-pentadiene).
