Calculate Digit Verification of CAS Registry Number 51972-65:
(7*5)+(6*1)+(5*9)+(4*7)+(3*2)+(2*6)+(1*5)=137
137 % 10 = 7
So 51972-65-7 is a valid CAS Registry Number.

Phthalimide derivatives and their use as plant growth regulants

-

, (2008/06/13)

The invention is a novel class of phthalimido derivatives represented by a formula: SPC1 Or SPC2 Wherein W is hydrogen or alkyl C1 -C4 ; X and X' each represent hydrogen, halogen, alkyl C1 -C4, CF3, alkoxy(C1 -C4), benzyloxy, di(C1 -C4)alkylamino, C1 -C4 alkylthio, hydroxy, C1 -C4 alkylsulfonyl, alkanoylamino C1 -C4 or nitro; Y is --COOR3, --CONHR8, --CONR3 R4, --CONHN(R5)2, --CONHN+(R6)3 . halide-, --CN or --COR7 with the proviso that at least one of X and X' is a substituent other than hydrogen; R1 and R2 each represent alkyl C1 -C4 or when taken together with the carbon to which they are attached form cycloalkyl C4 -C11 optionally substituted with methyl; R3 and R4 each represent hydrogen or alkyl C1 -C4 ; R5 and R6 each represent alkyl C1 -C2 ; R7 is halogen and R8 is --CH3 or SPC3 Where Z and Z' are hydrogen, alkyl C1 -C2, halogen, --CF3 or --OCH3, is a single or double bond with the proviso that there be only 0 or 1 double bond in the ring and a method for regulating the growth of plants with these compounds and with compounds having the above structure wherein X and X' each represent hydrogen.
