107960-33-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107960-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,6 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107960-33:
(8*1)+(7*0)+(6*7)+(5*9)+(4*6)+(3*0)+(2*3)+(1*3)=128
128 % 10 = 8
So 107960-33-8 is a valid CAS Registry Number.

Green synthetic method of kresoxim-methyl

-

Paragraph 0040-0042; 0062; 0063; 0064, (2019/11/13)

The invention belongs to the technical field of fine chemical engineering, and particularly relates to a green synthetic method of kresoxim-methyl. The method comprises the following steps: carrying out nitrous nitrification by using 2-methylbenzyl cyanide as an initial raw material, carrying out methylation, carrying out hydrolytic methylation or hydrolytic esterification, carrying out bromination and carrying out an etherification reaction to obtain the high-content kresoxim-methyl. The method provided by the invention has a short reaction period, a high conversion rate, and excellent product quality, changes the defect that high-concentration hydrochloric acid gas is used for preparation in a traditional process, and has the advantages of simple operation steps, simple equipment, low energy consumption, a short period, high productivity and environmental protection.

Reaction of the Silver Salts of Arylnitroacetonitriles with 9-Bromofluorene. Synthesis of 9-(α-Cyanoarylidene)fluorenes

Lianis, Pygmalion S.,Rodios, Nestor A.,Alexandrou, Nicholas E.

, p. 537 - 540 (2007/10/02)

The silver salts 1a-d react with 9-bromofluorene to give both C- and O-alkylated products 2 and 3.The latter decompose to yield 9-fluorenone and the α-cyanooximes 5.The products 2 upon treatment with NaOH/EtOH eliminate HNO2 to afford 9-(α-cyanoarylidene)fluorenes 4 in 80percent yield. 9-Chloro-9-phenylfluorene reacts with salt 1a to give only C-alkylated product 6 in 70percent yield.
