Check Digit Verification of cas no

The CAS Registry Mumber 256419-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,4,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 256419-20:
(8*2)+(7*5)+(6*6)+(5*4)+(4*1)+(3*9)+(2*2)+(1*0)=142
142 % 10 = 2
So 256419-20-2 is a valid CAS Registry Number.

Backbone stabilized peptidomimetics containing statine-like structural elements: Diastereospecific synthesis of trisubstituted cyclic ureas and 1,4-diazepan-2-ones

Scholz, Dieter,Hecht, Peter,Schmidt, Hannelore,Billich, Andreas

, p. 1283 - 1300 (2007/10/03)

2-Aminobenzyl substituted 4-amino-3-hydroxy-5-phenyl pentanoic acid (AHPPA) is the central structural element of highly active HIV-protease inhibitors. To obtain conformationally less flexible staline analogs, we stabilized AHPPA via ring formations, e.g.
