209474-75-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 209474-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,4,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 209474-75:
(8*2)+(7*0)+(6*9)+(5*4)+(4*7)+(3*4)+(2*7)+(1*5)=149
149 % 10 = 9
So 209474-75-9 is a valid CAS Registry Number.

Z-selective intramolecular Horner-Wadsworth-Emmons reaction for the synthesis of macrocyclic alkenes

Ando, Kaori,Sato, Kaori

, p. 1284 - 1287 (2011/03/22)

The Z-selective intramolecular Horner-Wadsworth-Emmons reaction of the substrates 7-12 (RO)2P(O)CHR′CO2Et (R′ = (CH2)nCHO) (R = Ph or o-tBuC6H4) gives the 13-18-membered cyclic alkenes selectively (up to Z:E = 97:3) in good yields using NaH in THF under high dilution conditions.

Pheromone synthesis, CXCIV. - Synthesis of the enantiomers of (Z)-21- methyl-8-pentatriacontene, the major component of the female-produced contact sex pheromone of the yellow-spotted longicorn beetle, Psacothea hilaris

Domon, Kenji,Takikawa, Hirosato,Mori, Kenji

, p. 981 - 984 (2007/10/03)

Both the enantiomers of (Z)-21-methyl-8-pentatriacontene (1), the major component of the female-produced contact sex pheromone of the yellow-spotted longicorn beetle (Psacothea hilaris), were synthesized by starting from the enantiomers of citronellol (2).
