Check Digit Verification of cas no

The CAS Registry Mumber 22117-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,1 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22117-22:
(7*2)+(6*2)+(5*1)+(4*1)+(3*7)+(2*2)+(1*2)=62
62 % 10 = 2
So 22117-22-2 is a valid CAS Registry Number.

meso-Phbox-Pd(II) catalyzed tandem carbonylative cyclization of 1-ethynyl-1-propargyl acetate

supporting information; experimental part, p. 3687 - 3689 (2009/02/05)

Palladium(II) catalyzed carbonylation of 1-ethynyl-1-propargyl acetate 1 is described; in the absence of the bisoxazoline (box) ligand, the second triple bond did not react, affording cyclic orthoesters 3 and 4. The use of meso-Phbox-Pd(II) strikingly changed the course of the reaction, yielding bicyclic lactone 2 by tandem carbonylative cyclization as a result of insertion of the second triple bond.
