Check Digit Verification of cas no
The CAS Registry Mumber 672-25-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 672-25:
(5*6)+(4*7)+(3*2)+(2*2)+(1*5)=73
73 % 10 = 3
So 672-25-3 is a valid CAS Registry Number.

Amide linkage of glycine-amino acid was synthesized by coupling of substituted 2-(aminomethyl)malononitrile as a C-terminal glycine unit and N-terminal amine using CsOAc and O2in an aqueous solution. This is a coupling reagent-free and catalyst-free peptide synthesisviaoxidative amide bond formation. Various tripeptides and tetrapeptides were synthesized efficiently and the sulfide moiety is inert even under an oxygen atmosphere.
