Purification Methods
Wash the salt with conductivity H2O by decantation until the supernatant gives a faint test for Ba2+ . Remove excess H2O in a vacuum (IMPORTANT), then heat at 100o and the last traces of H2O are removed in a vacuum desiccator over P2O5. Store it over KOH. It disproportionates in hot H2O or dilute acid into Ba(MnO2)2 and MnO2, and is a mild oxidant. [Schlezinger & Siems J Am Chem Soc 46 1965 1924, Nyholm & Woolliams Inorg Synth XI 56 1968.]
Check Digit Verification of cas no
The CAS Registry Mumber 7787-35-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7787-35:
(6*7)+(5*7)+(4*8)+(3*7)+(2*3)+(1*5)=141
141 % 10 = 1
So 7787-35-1 is a valid CAS Registry Number.
