Check Digit Verification of cas no
The CAS Registry Mumber 2750-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2750-81:
(6*2)+(5*7)+(4*5)+(3*0)+(2*8)+(1*1)=84
84 % 10 = 4
So 2750-81-4 is a valid CAS Registry Number.

Continuous reduction process
-
, (2008/06/13)
A process for the reduction of aromatic nitro compounds to amino compounds in the liquid phase using iron as reducing agent, which comprises carrying out the reduction continuously such that the reducing iron, based on the amount of nitro compound present in the reactor, is present in an amount substantially in excess of the stoichiometric amount, and effecting the continuous removal of the reaction products such that the substantial excess of reducing iron is also constantly present in the reactor during the reduction.
