Check Digit Verification of cas no

The CAS Registry Mumber 117679-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,7 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117679-97:
(8*1)+(7*1)+(6*7)+(5*6)+(4*7)+(3*9)+(2*9)+(1*7)=167
167 % 10 = 7
So 117679-97-7 is a valid CAS Registry Number.

Spermexatin and Spermexatol: New Synthetic Spermidine-Based Siderophore Analogues

Sharma, Sushil K.,Miller, Marvin J.,Payne, Shelley M.

, p. 357 - 367 (2007/10/02)

Syntheses of hexanediamine-based dihydroxamate (Hexamate), spermidine-based trihydroxamate (Spermexatins), and spermidine-based mixed siderophore analogues (Spermexatols) are described.Key intermediates include the N-hydroxysuccinimide esters of various hydroxamic acids, e.g., malonohydroxamate, succinohydroxamate, and glutarohydroxamate.These intermediates were synthesized, characterized, and incorporated as the ligating chains on spermidine.Also, mixed iron chelating compounds (Spermexatols) with both catechol and hydroxamic acid side chains were synthesized.Thereagent carbobenzoxyimidazole was employed to distinguish between the primary and secondary amino groups of spermidine.The ability of these iron chelators to stimulate microbial growth is also described.
