191939-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191939-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,9,3 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 191939-02:
(8*1)+(7*9)+(6*1)+(5*9)+(4*3)+(3*9)+(2*0)+(1*2)=163
163 % 10 = 3
So 191939-02-3 is a valid CAS Registry Number.

Synthesis of manoalide using a 1,2-metallate rearrangement
Pommier, Agnes,Kocienski, Philip J.
, p. 1139 - 1140 (2007/10/03)
Manoalide, a marine antiinflammatory sesterterpenoid, has been synthesised using a 1,2-metallate rearrangement of a higher order cuprate and a Pd0-catalysed carbonylation of an iodo alkene to generate the central dihydropyranone ring.
