131287-34-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131287-34-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,8 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 131287-34:
(8*1)+(7*3)+(6*1)+(5*2)+(4*8)+(3*7)+(2*3)+(1*4)=108
108 % 10 = 8
So 131287-34-8 is a valid CAS Registry Number.

STEREOISOMERS OF PENTAFLUOROBENZALDEHYDE AND PENTAFLUOROACETOPHENONE PHENYLHYDRAZONES
Petrenko, N. I.,Gerasimova, T. N.
, p. 359 - 366 (2007/10/02)
The interaction of pentafluorobenzaldehyde or 2,3,4,5,6-pentafluoroacetophenone with phenylhydrazine leads to isomer mixtures of the corresponding phenylhydrazones.Stereochemical assignments are based upon spectral and chemical data.
