Check Digit Verification of cas no

The CAS Registry Mumber 1374415-48-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,4,1 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1374415-48:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*1)+(3*5)+(2*4)+(1*8)=161
161 % 10 = 1
So 1374415-48-1 is a valid CAS Registry Number.

Preparation of new 1,4-diazocanes as scaffolds for combinatorial chemistry

Penning, Miriam,Christoffers, Jens

experimental part, p. 1809 - 1818 (2012/05/04)

Hexahydro-2-oxo-1,4-diazocin-6-carboxylic acid constitutes a conformationally rigid, crown-shaped scaffold. An orthogonally protected (Boc at N-4 and methyl ester at 6-CO2H) representative was prepared by ring expansion of a 3-pyrrolidone-derived 1,4-diketone with MeNH2. After deprotection, this building block was further diversified by reductive aminations and amidations and by sulfonamide and urea formation. Furthermore, the 6-CO2H function was transformed into a 6-NHCbz group in one step by carboxamide degradation in the presence of BnOH. An example of a cyclic tripeptoidic structure was synthesized by amidation with N-Boc-β-alanine and glycine methyl ester. Structural features of the eight-membered heterocycle were established by single-crystal X-ray structure analysis of a 4-bromoaniline derivative.
