Check Digit Verification of cas no
The CAS Registry Mumber 55944-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,4 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55944-43:
(7*5)+(6*5)+(5*9)+(4*4)+(3*4)+(2*4)+(1*3)=149
149 % 10 = 9
So 55944-43-9 is a valid CAS Registry Number.

Reaction of 1-bromo-1,2-dienes with alkylcuprates as a regio- and stereo-selective route to acetylenic or allenic compounds
Polizzi, Carmela,Consoloni, Carla,Lardicci, Luciano,Caporusso, Anna Maria
, p. 289 - 304 (2007/10/02)
Alkylcuprates react with 1-bromo-1,2-dienes to give allenic and/or acetylenic products.The selectivity of the crosscoupling is markedly dependent on the nature of the copper reagent, which plays a prominent role in determining both the regio- and the stereo-chemistry.The preparative aspects of these copper-induced reactions are discussed and their possible mechanism discussed.
