Uses
DL-Cysteine-3,3-d2 is the labelled form of DL-Cysteine (C995015). Cysteine is a non-essential amino acid that can be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available. Cysteine is commonly used as a precursor in the food and pharmaceutical industries. Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours.
Check Digit Verification of cas no
The CAS Registry Mumber 124051-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,5 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124051-54:
(8*1)+(7*2)+(6*4)+(5*0)+(4*5)+(3*1)+(2*5)+(1*4)=83
83 % 10 = 3
So 124051-54-3 is a valid CAS Registry Number.
