166272-95-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 166272-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,2,7 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 166272-95:
(8*1)+(7*6)+(6*6)+(5*2)+(4*7)+(3*2)+(2*9)+(1*5)=153
153 % 10 = 3
So 166272-95-3 is a valid CAS Registry Number.

Diethyl 2-oxopent-3-ynedioate: Synthesis and first cyclizations of a novel, reactive alkyne

Blitzke,Sicker,Wilde

, p. 236 - 238 (1995)

Diethyl 2-oxopent-3-ynedioate (3), the carbonyl homologue of diethyl acetylenedicarboxylate, is prepared by thermolysis of bis(ethoxalyl)methylenetriphenylphosphorane (2) and is found to be a reactive building block. Diels-Alder reaction of its alkyne unit with 1,3-diphenylisobenzofuran affords the cycloadduct 4, whereas reaction with binucleophiles such as ortho-XH-anilines (X = O,NH,S) leads to the incorporation of the oxoalkyne C3 -segment into the heterocycles 5-7.
