Check Digit Verification of cas no

The CAS Registry Mumber 29541-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,4 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29541-97:
(7*2)+(6*9)+(5*5)+(4*4)+(3*1)+(2*9)+(1*7)=137
137 % 10 = 7
So 29541-97-7 is a valid CAS Registry Number.

Pheromone components of the wheat stem sawfly: Identification, electrophysiology, and field bioassay

Cosse, Allard A.,Bartelt, Robert J.,Weaver, David K.,Zilkowski, Bruce W.

, p. 407 - 423 (2002)

Volatiles collections and cuticular extracts of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), were analyzed by coupled gas chromatographic-electroantennographic detection (GC-EAD) in order to detect possible pheromone components of

Method for synthesizing (9Z, 12E)-9,12-tetradecadien-1-ol acetate

-

, (2020/06/16)

The invention belongs to the technical field of green pesticide synthesis, and discloses a novel method for synthesizing (9Z, 12E)-9,12-tetradecadien-1-ol acetate. According to the method, malonic acid and 9-bromo-1-nonyl alcohol are used as two starting raw materials. The method comprises the following steps: carrying out a Knoevenagel condensation reaction on malonic acid and propionaldehyde inthe presence of piperidine acetate to generate (E)-3-pentenoic acid, then carrying out lithium aluminum hydride reduction to obtain (E)-3-penten-1-ol, carrying out bromination reaction, and refluxingwith triphenylphosphine in acetonitrile to obtain (E)-3-pentenyltriphenylphosphine bromide; carrying out a PCC oxidation reaction on 9-bromo-1-nonanol to obtain 9-bromononanal, and then reacting the 9-bromononanal with potassium acetate to obtain 9-acetoxynonanal; and finally, carrying out a Wittig reaction on (E)-3-pentenyltriphenylphosphine bromide and 9-acetoxynonanal so as to obtain (9Z, 12E)-9,12-tetradecadien-1-ol acetate. An E-type double bond is constructed by utilizing the Knoevenagel condensation reaction of malonic acid and propionaldehyde, and the method has the advantages of mildreaction conditions, environmental friendliness, simple synthetic route and the like.

Tandem application of C-C bond-forming reactions with reductive ozonolysis

Willand-Charnley, Rachel,Dussault, Patrick H.

, p. 42 - 47 (2013/03/29)

Several variants of reductive ozonolysis, defined here as the in situ generation of aldehydes or ketones during ozonolytic cleavage of alkenes, are demonstrated to work effectively in tandem with a number of C-C bond-forming reactions. For reactions involving basic nucleophiles (1,2- addition of Grignard reagents, Wittig or Horner-Emmons olefinations, and directed aldol reactions of lithium enolates), the one-pot process offers a rapid and high-yielding alternative to traditional two-step protocols.
