L-Cysteine, S-(3-methoxy-3-oxopropyl)-, also known as L-cysteine methyl ester, is a chemical compound derived from the amino acid L-cysteine. It is characterized by the presence of a 3-methoxy-3-oxopropyl group attached to the sulfur atom of the cysteine molecule. This modification results in a compound that retains the thiol group (-SH) of L-cysteine, which is crucial for its biological activity and reactivity. L-cysteine methyl ester is often used in biochemical research and pharmaceutical applications due to its ability to act as a precursor for the synthesis of other cysteine-containing compounds and its potential role in modulating protein function through S-alkylation.

Check Digit Verification of cas no

The CAS Registry Mumber 1625-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1625-74:
(6*1)+(5*6)+(4*2)+(3*5)+(2*7)+(1*4)=77
77 % 10 = 7
So 1625-74-7 is a valid CAS Registry Number.
