Check Digit Verification of cas no

The CAS Registry Mumber 1723-42-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,2 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1723-42:
(6*1)+(5*7)+(4*2)+(3*3)+(2*4)+(1*2)=68
68 % 10 = 8
So 1723-42-8 is a valid CAS Registry Number.

Overcoming regioselectivity issues inherent in bis-Troeger's base preparation

Havlik, Martin,Kral, Vladimir,Dolensky, Bohumil

, p. 4867 - 4870 (2007/10/03)

(Figure Presented) Bis-Troeger's base derivatives are a new family of molecular tweezers. A major drawback to their study is a lack of commercially available precursors, ortho-nitrocarboxylic acids. A reverse synthetic strategy starting from known dinitrodicarboxylic acids, which circumvents this problem, is presented. Via this methodology regioisomeric bis-TB derivatives can be prepared selectively, using only common aromatic amines that are typically commercially available.
