Hept-2-yn-1-ylpropanedioic acid is a complex organic compound with the molecular formula C10H14O4. It is characterized by a hept-2-yn-1-yl group, which is a seven-carbon chain with a triple bond at the second carbon, attached to a propanedioic acid moiety. Propanedioic acid, also known as malonic acid, is a dicarboxylic acid with two carboxyl groups. The combination of these functional groups results in a molecule that has potential applications in the synthesis of various organic compounds and pharmaceuticals. The unique structure of hept-2-yn-1-ylpropanedioic acid, with its triple bond and dicarboxylic acid component, may also be of interest in materials science and chemical research.

7499-20-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7499-20-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7499-20:
(6*7)+(5*4)+(4*9)+(3*9)+(2*2)+(1*0)=129
129 % 10 = 9
So 7499-20-9 is a valid CAS Registry Number.

Catalytic asymmetric protonation of chiral calcium enolates via 1,4-addition of malonates

Poisson, Thomas,Yamashita, Yasuhiro,Kobayashi, Shu

supporting information; experimental part, p. 7890 - 7892 (2010/08/05)

Catalytic asymmetric protonation of chiral calcium enolates was performed. Chiral calcium enolates, prepared in situ from imides and malonates via 1,4-addition in the presence of catalytic amounts of Ca(OEt)2, Ph-PyBox, and achiral phenol, were smoothly protonated to afford adducts bearing tertiary asymmetric carbons in high yields with high enantioselectivities. The adducts were readily converted to optically active 2-substituted 1,5-dicarboxylic acid derivatives.
