Check Digit Verification of cas no

The CAS Registry Mumber 131796-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,9 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131796-81:
(8*1)+(7*3)+(6*1)+(5*7)+(4*9)+(3*6)+(2*8)+(1*1)=141
141 % 10 = 1
So 131796-81-1 is a valid CAS Registry Number.

Dihydropyridine 5a was found to be an inhibitor of neuropeptide Y1 binding in a high throughput 125I-PYY screening assay. Structure-activity studies around certain portions of the dihydropyridine chemotype identified BMS-193885 (6e)

Process for preparation of enantiomerically pure polysubstituted 1,4-dihydropyridines

-

, (2008/06/13)

A process for the optical resolution of racemic 1,4-dihydropyridines, containing isothioureido groups. Salification of racemic isothioureas with optically active acids produces diasteroisomeric mixtures of isothiouronium salts, that, using conventional techniques, are separated in the individual components to give optically pure isothioureides of 1,4-dihydropyridines and salts thereof with conventional acids. Said optically pure 1,4-dihydropyridines can then be subjected to desulphuration and to different transformations to give to other enantiomerically pure and therapeutically useful 1,4-dihydropyridines.
