81467-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81467-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,6 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81467-90:
(7*8)+(6*1)+(5*4)+(4*6)+(3*7)+(2*9)+(1*0)=145
145 % 10 = 5
So 81467-90-5 is a valid CAS Registry Number.

Dimethylhydrazones of Substituted 4-Phenyl-3-buten-2-ones
Unterhalt, Bernard
, p. 178 - 181 (2007/10/02)
Some substituted 4-phenyl-3-buten-2one dimethylhydrazones 2 are synthesized, and the separation of the liquid E/Z isomers is attempted. (E)-4-(4'-Methylphenyl)-3-buten-2-one dimethylhydrazone (4) crystallizes, and its (1)H-, (13)C- and (15)N-nmr spectra a
