124648-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124648-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,4 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124648-08:
(8*1)+(7*2)+(6*4)+(5*6)+(4*4)+(3*8)+(2*0)+(1*8)=124
124 % 10 = 4
So 124648-08-4 is a valid CAS Registry Number.

Assignment of Stereochemistry to Cyclohexenylidenecyanoacetates by 1H NMR Spectroscopy
Bardakos, Vassilios,Sandris, Constantine
, p. 339 - 343 (2007/10/02)
The stereochemistry of various pairs of isomeric 2-cyclohexen-1-ylidenecyanoacetates was assigned using 1H NMR spectroscopy.The isomers with the γ-methylene or the γ-vinyl protons cis to the carbalkoxy group were found to have the signals of these protons
