Check Digit Verification of cas no

The CAS Registry Mumber 166881-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,8,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 166881-52:
(8*1)+(7*6)+(6*6)+(5*8)+(4*8)+(3*1)+(2*5)+(1*2)=173
173 % 10 = 3
So 166881-52-3 is a valid CAS Registry Number.

A new approach to Hmb-backbone protection of peptides: Synthesis and reactivity of N(α)-Fmoc-N(α)-(Hmb)amino acids

Nicolas, Ernesto,Pujades, Montse,Bacardit, Jordi,Giralt, Ernest,Albericio, Fernando

, p. 2317 - 2320 (2007/10/03)

The use of N-Fmoc-N-(Hmb)amino acids for the introduction of the Hmb backbone protection into peptides during solid-phase synthesis is described. An efficient two step synthesis of these derivatives is reported and their coupling to the peptide chain is studied.
