Check Digit Verification of cas no
The CAS Registry Mumber 5314-37-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,1 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5314-37:
(6*5)+(5*3)+(4*1)+(3*4)+(2*3)+(1*7)=74
74 % 10 = 4
So 5314-37-4 is a valid CAS Registry Number.

Preparation of linear aromatic disulfonic acids: New linker molecules for metal-organic frameworks
Muesmann, Thomas W.T.,Wickleder, Mathias S.,Christoffers, Jens
, p. 2775 - 2780 (2011/10/31)
Four linear aromatic disulfonic acids were prepared, which are structurally similar to dicarboxylic acids commonly used as linker molecules for metal-organic frameworks. 4,4-Biphenyldisulfonic acid was prepared in three steps from 4,4-dibromobiphenyl (54% overall yield). Direct sulfonation of terphenyl gave the respective all-para-constituted disulfonic acid in 73% yield. Tolane-4,4-disulfonic acid was obtained by a three-step sequence consisting of Sonogashira coupling, oxidative degradation of a thioester, and hydrolysis in 20% overall yield. By using a Glaser coupling, the bis(4-sulfophenyl)butadiyne was analogously prepared in 30% overall yield. Georg Thieme Verlag Stuttgart - New York.
