α-Hydroxyaminobuttersaeure-t-butylester, also known as α-hydroxy-α-amino-N-t-butylbutanamide, is an organic compound with the chemical formula C9H19NO2. It is a derivative of α-amino acids, featuring a hydroxyl group and a t-butyl ester group attached to the α-carbon. α-Hydroxyaminobuttersaeure-t-butylester is of interest in the field of organic chemistry, particularly in the synthesis of various pharmaceuticals and agrochemicals, due to its potential to act as a chiral building block or a protecting group. The t-butyl ester group provides stability and can be selectively removed under acidic conditions, making it a useful protecting group for the carboxylic acid function in multi-step syntheses.

Check Digit Verification of cas no

The CAS Registry Mumber 55424-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,2 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55424-16:
(7*5)+(6*5)+(5*4)+(4*2)+(3*4)+(2*1)+(1*6)=113
113 % 10 = 3
So 55424-16-3 is a valid CAS Registry Number.
