Check Digit Verification of cas no
The CAS Registry Mumber 171200-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,2,0 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171200-90:
(8*1)+(7*7)+(6*1)+(5*2)+(4*0)+(3*0)+(2*9)+(1*0)=91
91 % 10 = 1
So 171200-90-1 is a valid CAS Registry Number.

A synthesis of (3R*,4R*)-Luffariolide E via 1,2-metallate rearrangement
Hareau-Vittini,Kocienski,Reid
, p. 1007 - 1013 (2007/10/02)
A key step in the synthesis of (3R*,4R*)-Luffariolide E is a 1,2-metallate rearrangement of a higher order cuprate to generate a trisubstituted double bond stereoselectively. The synthetic product is a diastereoisomer of the natural marine cytotoxic agent (3S,4R)-Luffariolide E.
