Calculate Digit Verification of CAS Registry Number 1028192-69:
(9*1)+(8*0)+(7*2)+(6*8)+(5*1)+(4*9)+(3*2)+(2*6)+(1*9)=139
139 % 10 = 9
So 1028192-69-9 is a valid CAS Registry Number.

Ultrasound assisted synthesis of 5,9-dimethylpentadecane and 5,9-dimethylhexadecane - The sex pheromones of Leucoptera coffeella

Doan, Nhuan Ngoc,Le, Thach Ngoc,Nguyen, Hao Cong,Hansen, Poul Erik,Duus, Fritz

, p. 2080 - 2088 (2007)

Racemic 5,9-dimethylpentadecane and 5,9-dimethylhexadecane, the major and minor constituents, respectively, of the sex pheromone of Leucoptera coffeella, have been synthesized from citronellol in 56-58% overall yield through six steps. Ultrasound irradiation efficiently supported tosylation of alcohols (two steps) as well as the subsequent cross coupling reactions with the pertinent Grignard reagents (also two steps).
