Check Digit Verification of cas no
The CAS Registry Mumber 84409-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,0 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84409-38:
(7*8)+(6*4)+(5*4)+(4*0)+(3*9)+(2*3)+(1*8)=141
141 % 10 = 1
So 84409-38-1 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.
