Check Digit Verification of cas no
The CAS Registry Mumber 5077-59-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,7 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5077-59:
(6*5)+(5*0)+(4*7)+(3*7)+(2*5)+(1*9)=98
98 % 10 = 8
So 5077-59-8 is a valid CAS Registry Number.

2,4-Dinitrophenylhydrazones: A Modified Method for the Preparation of These Derivatives and an Explanation of Previous Conflicting Results
Behforouz, Mohammad,Bolan Joseph L.,Flynt, Michael S.
, p. 1186 - 1189 (1985)
Conventional methods for forming 2,4-dinitrophenylhydrazones (2,4-DNPH's) usually leave traces of acids complexed with the derivatives and cause variable melting points.A bicarbonate wash of the 2,4-DNPH crystals removes the acid and reproducibly gives de
