27220-69-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27220-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27220-69:
(7*2)+(6*7)+(5*2)+(4*2)+(3*0)+(2*6)+(1*9)=95
95 % 10 = 5
So 27220-69-5 is a valid CAS Registry Number.

Mechanoenzymatic peptide and amide bond formation

Hernández, José G.,Ardila-Fierro, Karen J.,Crawford, Deborah,James, Stuart L.,Bolm, Carsten

supporting information, p. 2620 - 2625 (2017/07/17)

Mechanochemical chemoenzymatic peptide and amide bond formation catalysed by papain was studied by ball milling. Despite the high-energy mixing experienced inside the ball mill, the biocatalyst proved stable and highly efficient to catalyse the formation of α,α- and α,β-dipeptides. This strategy was further extended to the enzymatic acylation of amines by milling, and to the mechanosynthesis of a derivative of the valuable dipeptide L-alanyl-l-glutamine.

Development of peptide 3D structure mimetics: Rational design of novel peptoid cholecystokinin receptor antagonists

Low,Black,Broughton,Buck,Davies,Dunstone,Hull,Kalindjian,McDonald,Pether,Shankley,Steel

, p. 3505 - 3517 (2007/10/03)

The two hormones cholecystokinin and gastrin share the same C-terminal sequence of amino acids, namely Gly29-Trp30-Met31-Asp32-Phe33-NH2. Nevertheless, this congruence has not precluded usi
