Check Digit Verification of cas no
The CAS Registry Mumber 89-45-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89-45:
(4*8)+(3*9)+(2*4)+(1*5)=72
72 % 10 = 2
So 89-45-2 is a valid CAS Registry Number.

Intramolecular Catalysis of Sulphate Diester Hydrolysis by One and Two Carboxy Groups. The Hydrolysis of Aryl 2-Carboxyphenyl Sulphates
Drummond, Jeremy N.,Kirby, Anthony J.
, p. 579 - 584 (2007/10/02)
The hydrolysis of aryl 2-carboxyphenyl (salicyl) sulphates is subject to efficient nucleophilic catalysis by the neighbouring carboxylate group.The intermediate cyclic acyl sulphate can be trapped with hydroxylamine.The reaction of disalicyl sulphate is further catalysed by the second carboxy group, acting, rather inefficiently, as a general acid.
