871506-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871506-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,5,0 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871506-42:
(8*8)+(7*7)+(6*1)+(5*5)+(4*0)+(3*6)+(2*4)+(1*2)=172
172 % 10 = 2
So 871506-42-2 is a valid CAS Registry Number.

A short synthesis of conjugated unsaturated amides and esters via triphenylphosphine-catalysed isomerisation of acetylenic pentafluorophenyl esters
Kazmaier, Uli
, p. 2305 - 2306 (2007/10/03)
Isomerisation of acetylenic pentafluorophenyl esters in the presence of phosphines gives rise to activated dienoic acids, which can be coupled directly with amines and alcohols in a simple one-pot procedure.
