Check Digit Verification of cas no
The CAS Registry Mumber 49540-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,5,4 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 49540-21:
(7*4)+(6*9)+(5*5)+(4*4)+(3*0)+(2*2)+(1*1)=128
128 % 10 = 8
So 49540-21-8 is a valid CAS Registry Number.

The invention relates to a new process for the preparation of hydroxymethylthiobutyric acid by sulphuric hydrolysis of hydroxymethylthiobutyronitrile.
Process for producing 2-hydroxy-4-methylthiobutanoic acid
-
, (2008/06/13)
Methyl 2-hydroxy-4-methylthiobutanoate and formamide are produced by means of reacting 2-hydroxy-4-methylthiobutanamide obtained by hydration of 2-hydroxy-4-methylthiobutyronitrile with methyl formate. Said methyl 2-hydroxy-4-methylthiobutanoate is hydrolyzed to give 2-hydroxy-4-methylthiobutanoic acid and methanol. No sulfuric acid is employed as a reacting agent, hence exhaustion of a large quantity of ammonium sulfate is prevented. Formamide and methanol thus produced can be recycled as reactants.
