131791-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131791-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,9 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131791-53:
(8*1)+(7*3)+(6*1)+(5*7)+(4*9)+(3*1)+(2*5)+(1*3)=122
122 % 10 = 2
So 131791-53-2 is a valid CAS Registry Number.

Palladium-catalyzed cyclizations of polyenynes. A palladium zipper
Trost, Barry M.,Shi, Yian
, p. 9421 - 9438 (2007/10/02)
The cycloisomerization of polyenynes with a catalyst derived from Pd(0), acetic acid, and a ligand to polycycles depends upon the juxtaposition of unsaturation. The process involves the stages of initiation (by addition of Pd-H to an acetylene), propagati
