L-Cysteine, ethyl-(9CI), also known as N-Ethyl-L-cysteine, is an organic compound with the chemical formula C5H11NO2S. It is a derivative of the amino acid L-cysteine, where the hydrogen atom of the amino group is replaced by an ethyl group (-CH2CH3). This modification results in a zwitterionic structure, with a positively charged amino group and a negatively charged carboxyl group, as well as a thiol group (-SH) that is characteristic of cysteine. L-Cysteine, ethyl-(9CI) is a colorless crystalline solid that is soluble in water and has various applications in the fields of biochemistry and pharmaceuticals, such as a building block for peptide synthesis and a precursor for the synthesis of other sulfur-containing compounds.

1320-75-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1320-75-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1320-75:
(6*1)+(5*3)+(4*2)+(3*0)+(2*7)+(1*5)=48
48 % 10 = 8
So 1320-75-8 is a valid CAS Registry Number.
