19996-03-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19996-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,9 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19996-03:
(7*1)+(6*9)+(5*9)+(4*9)+(3*6)+(2*0)+(1*3)=163
163 % 10 = 3
So 19996-03-3 is a valid CAS Registry Number.

Determination of protonation states of iminosugar-enzyme complexes using photoinduced electron transfer

Wang, Bo,Olsen, Jacob Ingemar,Laursen, Bo W.,Navarro Poulsen, Jens Christian,Bols, Mikael

, p. 7383 - 7393 (2017/10/30)

A series of N-alkylated analogues of 1-deoxynojirimycin containing a fluorescent 10-chloro-9-anthracene group in the N-alkyl substituent were prepared. The anthracene group acted as a reporting group for protonation at the nitrogen in the iminosugar because an unprotonated amine was found to quench fluorescence by photoinduced electron transfer. The new compounds were found to inhibit β-glucosidase from Phanerochaete chrysosporium and α-glucosidase from Aspergillus Niger, with Ki values in the low micro- to nanomolar range. Fluorescence and inhibition versus pH studies of the β-glucosidase-iminosugar complexes revealed that the amino group in the inhibitor is unprotonated when bound, while one of the active site carboxylates is protonated.
