Calculate Digit Verification of CAS Registry Number 91175-73:
(7*9)+(6*1)+(5*1)+(4*7)+(3*5)+(2*7)+(1*3)=134
134 % 10 = 4
So 91175-73-4 is a valid CAS Registry Number.

Insect Growth Regulators. XIII - Juvenoids with Cyclopentene Ring. Synthesis of Alkyl ω-(2,2,3-Trimethyl-Cyclopent-3-en-1-yl)-2-alkenoates and ω-(2,2,3-Trimethyl-Cyclopent-3-en-1-yl)alkyl Phenyl Ethers

Derdzinski, K.,Wawrzenczyk, C.,Zabza, A.,et al.

, p. 196 - 212 (2007/10/02)

Neue Analoga der Insektenjuvenilhormone mit dem Cyclopentenring wurden aus dem (2,2,3-Trimethyl-cyclopent-3-en-1-yl)acetonitril (1) durch eine mehrstufige Synthese erhalten.Die Ether 7a-c, 8a, b, 15a-c und 34a, b wurden durch Alkylierung der 4-substituierten Phenolate mit entsprechenden Tosylaten oder Bromiden synthetisiert.Die Ester 11a-c, 12a, b, 21a-c, 23a-c, 28a, b, 29, 27 und 33a, b mit unterschiedlicher Kettenlaenge wurden durch die Wadsworth-Emmons-Reaktion der Ketone 11, 12, 19, 26, 27, 32 bzw. des Aldehydes 16 mit entsprechenden Phosphonsaeurealkylestern erhalten.
