The CAS Registry Mumber 87176-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,7 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87176-68:
(7*8)+(6*7)+(5*1)+(4*7)+(3*6)+(2*6)+(1*8)=169
169 % 10 = 9
So 87176-68-9 is a valid CAS Registry Number.

Reactions with Phosphine Alkylenes, XLII. A Sequence for the Preparation of Acetylenes Starting from Carboxylic Chlorides and Phosphorus Ylides via 1,2-Diketones.

Bestmann, Hans Juergen,Kumar, Kamlesh,Kisielowski, Lothar

, p. 2378 - 2382 (2007/10/02)

Phosphorus ylides 1 and carboxylic chlorides 2 react with transylidation to give acyl ylides 3 which are oxidized with the adduct of ozone to triphenyl phosphite to yield 1,2-diketones 5.These are converted into the bis(hydrazones) 6 which are oxidized with O2/CuCl in pyridine giving acetylenes 7.
