Check Digit Verification of cas no

The CAS Registry Mumber 254112-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,1,1 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 254112-89:
(8*2)+(7*5)+(6*4)+(5*1)+(4*1)+(3*2)+(2*8)+(1*9)=115
115 % 10 = 5
So 254112-89-5 is a valid CAS Registry Number.

α-alkyl-α-amino-β-lactam peptides: Design, synthesis, and conformational features

Palomo, Claudio,Aizpurua, Jesus M.,Benito, Ana,Galarza, Regina,Khamrai, Uttam K.,Vazquez, Jordi,De Pascual-Teresa, Beatriz,Nieto, Pedro M.,Linden, Anthony

, p. 3056 - 3058 (2007/10/03)

Remarkable asymmetric induction is achieved in the alkylation of the lithium enolate of the β-lactam 1. This allows the first time access to a new family of peptidomimetics 2 with predictable conformational constraints.
