Check Digit Verification of cas no
The CAS Registry Mumber 548-25-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 548-25:
(5*5)+(4*4)+(3*8)+(2*2)+(1*5)=74
74 % 10 = 4
So 548-25-4 is a valid CAS Registry Number.

Rose Bengal analogs and vesicular glutamate transporters (VGLUTs)
Pietrancosta, Nicolas,Kessler, Albane,Favre-Besse, Franck-Cyril,Triballeau, Nicolas,Quentin, Thomas,Giros, Bruno,Mestikawy, Salah El,Acher, Francine C.

Vesicular glutamate transporters (VGLUTs) allow the loading of presynaptic glutamate vesicles and thus play a critical role in glutamatergic synaptic transmission. Rose Bengal (RB) is the most potent known VGLUT inhibitor (K i 25 nM); therefore we designed, synthesized and tested in brain preparations, a series of analogs based on this scaffold. We showed that among the two tautomers of RB, the carboxylic and not the lactonic form is active against VGLUTs and generated a pharmacophore model to determine the minimal structure requirements. We also tested RB specificity in other neurotransmitter uptake systems. RB proved to potently inhibit VMAT (Ki 64 nM) but weakly VACHT (Ki >9.7 μM) and may be a useful tool in glutamate/acetylcholine co-transmission studies.
