Check Digit Verification of cas no

The CAS Registry Mumber 1289679-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,6,7 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1289679-28:
(9*1)+(8*2)+(7*8)+(6*9)+(5*6)+(4*7)+(3*9)+(2*2)+(1*8)=232
232 % 10 = 2
So 1289679-28-2 is a valid CAS Registry Number.

Unprecedented synthesis of alkynylphosphine-boranes through room-temperature oxidative alkynylation

Jouvin, Kevin,Veillard, Romain,Theunissen, Cedric,Alayrac, Carole,Gaumont, Annie-Claude,Evano, Gwilherm

supporting information, p. 4592 - 4595 (2013/09/24)

An original and user-friendly synthesis of alkynylphosphine-boranes, useful building blocks in organic synthesis, based on an oxidative P-alkynylation reaction with readily available copper acetylides is reported. The ability of a secondary phosphine protected with a borane to undergo oxidative coupling without oxidation of the P-moiety is demonstrated for the first time. The reaction, which proceeds at room temperature, is applicable to the preparation of enantioenriched and structurally complex alkynylphosphine-boranes.

Copper-catalyzed synthesis of alkynylphosphine derivatives: Unprecedented use of nucleophilic phosphorus compounds

Bernoud, Elise,Alayrac, Carole,Delacroix, Olivier,Gaumont, Annie-Claude

supporting information; experimental part, p. 3239 - 3241 (2011/05/07)

A new and smooth approach towards alkynylphosphine derivatives is described. It relies on the unprecedented catalytic coupling of secondary phosphine boranes with alkynyl bromides using the CuI/1,10-phenanthroline couple.
