Check Digit Verification of cas no

The CAS Registry Mumber 54519-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,1 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54519-52:
(7*5)+(6*4)+(5*5)+(4*1)+(3*9)+(2*5)+(1*2)=127
127 % 10 = 7
So 54519-52-7 is a valid CAS Registry Number.

Synthesis of mono- and di-potassium salts and methoxy adducts of sulfur-bridged biphenols by selective deprotonation

Arnold, Polly L.,Hall, Jonathan J.,Natrajan, Louise S.,Blake, Alexander J.,Wilson, Claire

, p. 1053 - 1055 (2003)

Mono- and di-potassium salts and methoxy adducts of sulfur-bridged biphenols by selective deprotonation were synthesized. Flame photometry analysis and a crystal x-ray structural determination were carried out to confirm the composition. Addition of an ethereal solution to a stirred suspension of stoichiometric KH in diethyl ether afforded an analytically pure pale yellow precipitate characterized as the mono-potassium salt. The non-macrocyclic ligands described show selective deprotonation chemistry, creating simple routes to tuneable, mono- or di-anionic acryloxide-based ligands.
