98977-53-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98977-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,7 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98977-53:
(7*9)+(6*8)+(5*9)+(4*7)+(3*7)+(2*5)+(1*3)=218
218 % 10 = 8
So 98977-53-8 is a valid CAS Registry Number.

Application of naftifine analogue in control of agricultural plant diseases

-

Paragraph 0011-0016; 0057-0060, (2020/07/21)

The invention discloses application of any compound of naftifine analogues H-01 to H-22 in control of agricultural plant fungal diseases. Biological activity tests indicate that the derivatives show certain inhibitory activity on the six plant diseases, i

Isothiourea-catalysed chemo- and enantioselective [2,3]-sigmatropic rearrangements of N,N-diallyl allylic ammonium ylides

West, Thomas H.,Spoehrle, Stéphanie S.M.,Smith, Andrew D.

, p. 4138 - 4149 (2017/06/29)

The isothiourea-catalysed chemo- and enantioselective [2,3]-sigmatropic rearrangement of N,N-diallyl allylic ammonium ylides is explored as a key part of a route to free functionalised α-amino esters and piperidines. The [2,3]-sigmatropic rearrangement pr

Copper-catalyzed hydroboration of propargyl-functionalized alkynes in water

Da Costa, Jessie S.,Braun, Roger K.,Horn, Pedro A.,Lüdtke, Diogo S.,Moro, Angélica V.

, p. 59935 - 59938 (2016/07/11)

The Cu-catalyzed hydroboration of alkynes in operationally simple and environmentally friendly conditions is reported. The reactions are performed in water, at room temperature, under micellar catalysis. Conditions to form the α or β borylated products se
