Check Digit Verification of cas no

The CAS Registry Mumber 137579-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,7 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137579-20:
(8*1)+(7*3)+(6*7)+(5*5)+(4*7)+(3*9)+(2*2)+(1*0)=155
155 % 10 = 5
So 137579-20-5 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 (1991)

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.
