80344-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80344-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,4 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80344-88:
(7*8)+(6*0)+(5*3)+(4*4)+(3*4)+(2*8)+(1*8)=123
123 % 10 = 3
So 80344-88-3 is a valid CAS Registry Number.

THE FORMATION OF CYCLOPENTENONES AND 3(2H)-FURANONES FROM ACETYLENIC PRECURSORS
Williams, D. R.,Abbaspour, A.,Jacobson, R. M.
, p. 3565 - 3568 (2007/10/02)
Acetylenic alcohols, obtained in high yield from condensations of 3,3-diethoxypropyne or 3,3-ethylenedioxybutyne with cyclic ketones, may be used as substrates for cyclopentenone annelation or spirofuranone synthesis.
