Check Digit Verification of cas no

The CAS Registry Mumber 948842-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,8,4 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 948842-84:
(8*9)+(7*4)+(6*8)+(5*8)+(4*4)+(3*2)+(2*8)+(1*4)=230
230 % 10 = 0
So 948842-84-0 is a valid CAS Registry Number.

Synthesis and evaluation of carbamoylmethylene linked prodrugs of BMS-582949, a clinical p38α inhibitor

Liu, Chunjian,Lin, James,Everlof, Gerry,Gesenberg, Christoph,Zhang, Hongjian,Marathe, Punit H.,Malley, Mary,Galella, Michael A.,McKinnon, Murray,Dodd, John H.,Barrish, Joel C.,Schieven, Gary L.,Leftheris, Katerina

A series of carbamoylmethylene linked prodrugs of 1 (BMS-582949), a clinical p38α inhibitor, were synthesized and evaluated. Though the phosphoryloxymethylene carbamates (3, 4, and 5) and α- aminoacyloxymethylene carbamates (22, 23, and 26) were found unstable at neutral pH values, fumaric acid derived acyloxymethylene carbamates (2, 28, and 31) were highly stable under both acidic and neutral conditions. Prodrugs 2 and 31 were also highly soluble at both acidic and neutral pH values. At a solution dose of 14.2 mpk (equivalent to 10 mpk of 1), 2 gave essentially the same exposure of 1 compared to dosing 10 mpk of 1 itself. At a suspension dose of 142 mpk (equivalent to 100 mpk of 1), 2 demonstrated that it could overcome the solubility issue associated with 1 and provide a much higher exposure of 1. To our knowledge, the unique type of prodrugs like 2, 28, and 31 was not reported in the past and could represent a novel prodrug approach for secondary amides, a class of molecules frequently identified as drug candidates.
