80557-04-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80557-04-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,5 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80557-04:
(7*8)+(6*0)+(5*5)+(4*5)+(3*7)+(2*0)+(1*4)=126
126 % 10 = 6
So 80557-04-6 is a valid CAS Registry Number.

The electrosynthesis of carboxylic acids from carbon dioxide and butadiene
Tilborg, W. J. M. van,Smit, C. J.
, p. 437 - 438 (2007/10/02)
Electroreduction of carbon dioxide in acetonitrile in the presence of butadiene gives rise to the formation of 3-pentenoic acid (2), 3-hexenedioic acid (3), and 3,7-decadienedioic and two isomeric C10-dicarboxylic acids (4) in high chemical yields.
