905291-66-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 905291-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,2,9 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 905291-66:
(8*9)+(7*0)+(6*5)+(5*2)+(4*9)+(3*1)+(2*6)+(1*6)=169
169 % 10 = 9
So 905291-66-9 is a valid CAS Registry Number.

A series of N-benzoyl 4-aminobutyric acid hydroxamate analogs were synthesized and evaluated as matrix metalloproteinase inhibitors. Synthetic work was focused on the chemical modification of the 4-aminobutyric acid part using easily available starting materials. As such, chemical modification was carried out using commercially available starting materials such as 4-aminobutyric acid, (+)- and (-)-malic acid, and d- and l-glutamic acid derivatives. Among the compounds tested, N-[4-(benzofuran-2-yl)benzoyl] 4-amino-4S-hydroxymethylbutyric acid hydroxamates derived from l-glutamic acid demonstrated more potent inhibitory activity against MMP-2 and MMP-9 compared with the corresponding 2S-hydroxy analogs or 3S-hydroxy analogs, respectively, which were derived from (-)-malic acid. Structure-activity relationship study is presented.
