Check Digit Verification of cas no

The CAS Registry Mumber 195005-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,0,0 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 195005-73:
(8*1)+(7*9)+(6*5)+(5*0)+(4*0)+(3*5)+(2*7)+(1*3)=133
133 % 10 = 3
So 195005-73-3 is a valid CAS Registry Number.

Synthesis of bicyclic tripeptides inspired by the ABC-ring system of vancomycin through ruthenium-based cyclization chemistries

Yang, Xin,Beroske, Lucas P.,Kemmink, Johan,Rijkers, Dirk T.S.,Liskamp, Rob M.J.

, p. 4542 - 4546 (2017)

The synthesis of a bicyclic tripeptide that mimics the ABC ring system of vancomycin is described by using a ring closing metathesis (RCM) – peptide coupling – ruthenium-catalyzed azide-alkyne cycloaddition (RuAAC) strategy.

Total synthesis of vancomycin - Part 1: Design and development of methodology

Nicolaou,Li, Hui,Boddy, Christopher N. C.,Ramanjulu, Joshi M.,Yue, Tai-Yuen,Natarajan, Swaminathan,Chu, Xin-Jie,Braese, Stefan,Ruebsam, Frank

o-Halosubstituted aromatic triazenes (e.g. I, Scheme 1) react with aryloxides (e.g. II, Scheme 1) in the presence of CuBr · Me2S, K2CO3 and pyridine in acetonitrile at reflux to afford biaryl ethers (e.g. V, Scheme 1). This general methodology (Tables 1 and 2) was applied to the construction of the C-O-D and D-O-E vancomycin model systems 37 (Scheme 2) and 50 (Scheme 3), demonstrating its potential in a projected total synthesis of vancomycin (1. Figure 1). For the construction of the vancomycin model AB biaryl ring system, a sequential strategy involving a Suzuki coupling of the C-O-D aryl iodide 74 (Scheme 7) and boronic acid 53 (Scheme 4), followed by macrolactamization was demonstrated, in which the preformed C-O-D ring framework served to preorganize the precursor for cyclization. The latter investigation led to Suzuki-coupling-based asymmetric synthesis of biaryl systems in which 2,2-bis(diphenylphosphino)-1,1'-binaphthyl (BINAP) was found to be the optimum ligand (Tables 3 and 4).
