762-40-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 762-40-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 762-40:
(5*7)+(4*6)+(3*2)+(2*4)+(1*0)=73
73 % 10 = 3
So 762-40-3 is a valid CAS Registry Number.

The Autoxidation of Hept-3-yne

Brose, Th.,Pritzkow, W.,Sebald, F.,Voerckel, V.

, p. 951 - 956 (2007/10/02)

In the reaction mixtures of the oxidation of hept-3-yne with molecular oxygen as products of the attack on the C-C triple bond heptane-3,4-dione, propionic and butyric acids and a very small amount of 2-ethylvaleric acid were found.Hept-2-en-4-one and hept-3-en-5-one were probably present, but could not be identified unambiguously.As in the case of the isomeric octynes the main primary reaction products were the hydroperoxides formed by attack on the C-H bonds in α-position to the CC triple bond.
