Check Digit Verification of cas no

The CAS Registry Mumber 956283-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,6,2,8 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 956283-76:
(8*9)+(7*5)+(6*6)+(5*2)+(4*8)+(3*3)+(2*7)+(1*6)=214
214 % 10 = 4
So 956283-76-4 is a valid CAS Registry Number.

Scalable synthesis of orthogonally protected β-methyllanthionines by indium(III)-mediated ring opening of aziridines

Li, Ziran,Gentry, Zachary,Murphy, Brennan,Vannieuwenhze, Michael S.

, p. 2200 - 2203 (2019)

Lantibiotics are a class of peptide antibiotics with activity against most Gram-positive bacteria. Lanthionine (Lan) and β-MeLan are unusual thioether-bridged, non-proteinogenic amino acids, which are characteristic features of lantibiotics. In this paper, we report the facile stereoselective synthesis of β-methyllanthionines with orthogonal protection by nucleophilic ring opening of aziridines. This method leads to an expedient access to β-methyllanthionines and allows production of over 30 g of β-methyllanthionine in a single batch.
