75761-39-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75761-39-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,6 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75761-39:
(7*7)+(6*5)+(5*7)+(4*6)+(3*1)+(2*3)+(1*9)=156
156 % 10 = 6
So 75761-39-6 is a valid CAS Registry Number.

Preparation and Stereochemistry of Some 1,1-Disubstituted Buta-1,3-dienes
Curry, Michael J.,Stevens, D.R.
, p. 1756 - 1760 (2007/10/02)
The preparation of five (E)- and five (Z)-1,1-disubstituted buta-1,3-dienes is described and their stereochemistry assigned.The effect of the Z-E isomerism on the chemical shifts in the 13C and 1H n.m.r. spectra is discussed.
