Check Digit Verification of cas no

The CAS Registry Mumber 198954-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,9,5 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 198954-99:
(8*1)+(7*9)+(6*8)+(5*9)+(4*5)+(3*4)+(2*9)+(1*9)=223
223 % 10 = 3
So 198954-99-3 is a valid CAS Registry Number.

Supramolecular catalysis of H/D exchange in pyruvate by macrocyclic polyamines involving a reactive iminium intermediate

Fenniri, Hicham,Dallaire, Carol,Funeriu, Daniel P.,Lehn, Jean-Marie

, p. 2073 - 2081 (2007/10/03)

The activity of a series of macrocyclic polyamines as catalysts for proton exchange has been investigated. Structural and physico-chemical studies demonstrate the ability of these receptors to recognize pyruvate, form a covalent iminium intermediate and catalyse H/D exchange at the CH3 position. The reaction follows Michaelis-Menten kinetics with a rate enhancement higher than 4.8 × 105 (kcat/kuncat). The process also represents a potential entry into the catalysis of aldol condensation reactions.
