Check Digit Verification of cas no

The CAS Registry Mumber 1070503-98-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,0,5,0 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1070503-98:
(9*1)+(8*0)+(7*7)+(6*0)+(5*5)+(4*0)+(3*3)+(2*9)+(1*8)=118
118 % 10 = 8
So 1070503-98-8 is a valid CAS Registry Number.

Total synthesis of exiguamines A and B inspired by catecholamine chemistry

Sofiyev, Vladimir,Lumb, Jean-Philip,Volgraf, Matthew,Trauner, Dirk

, p. 4999 - 5005 (2012/06/04)

The evolution of a total synthesis of the exiguamines, two structurally unusual natural products that are highly active inhibitors of indolamine-2,3-dioxygenase (IDO), is described. The ultimately successful strategy involves advanced cross-coupling methodology and features a potentially biosynthetic tautomerization/electrocyclization cascade reaction that forms two heterocycles and installs a quaternary ammonium ion in a single synthetic operation.
