Check Digit Verification of cas no

The CAS Registry Mumber 123872-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,7 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123872-89:
(8*1)+(7*2)+(6*3)+(5*8)+(4*7)+(3*2)+(2*8)+(1*9)=139
139 % 10 = 9
So 123872-89-9 is a valid CAS Registry Number.

EFFICIENT ROUTES TO THE ARNSTEINS'S TRIPEPTIDE δ-(L-α-AMINOADIPYL)-L-CYSTEINYL-D-VALINE (LLD ACV) FROM THE OXIDATION PRODUCTS OF L-LYSINE DERIVATIVES

Liberek, Bogdan,Kasprzykowska, Regina,Wisniewski, Kazimierz

, p. 2857 - 2862 (2007/10/02)

Two efficient syntheses of the linear tripeptide precursor of penam and cephem antibiotics are presented.The routes are characterised by the use of L-lysine derivatives, Z-L-Lys(Z)-OH and H-L-Lys(Z)-OH as starting materials.By the permanganate oxidation t
