Check Digit Verification of cas no

The CAS Registry Mumber 1258869-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,8,6 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1258869-68:
(9*1)+(8*2)+(7*5)+(6*8)+(5*8)+(4*6)+(3*9)+(2*6)+(1*8)=219
219 % 10 = 9
So 1258869-68-9 is a valid CAS Registry Number.

Synthesis and biological activity of novel 1H-1,4-diazepines containing benzene sulfonyl piperazine moiety

Saingar, Shalini,Kumar, Rajesh,Joshi, Yogesh Chandra

, p. 975 - 980 (2012/05/20)

The synthesis of biologically active 1H-1,4-diazepines 6a-e in good yield, from the heterocyclization reaction of [N4-(4-acetylamino) benzene sulfonyl) piperazinyl- N1-propyl]-1,3-dialkyl/aryl propane-1,3-dione 5a-e and ethylenediamine (EDA) in the presence of silica sulphuric acid (SSA) is described. The novel β-diketones/β-ketoesters 5a-e were synthesized by the condensation reaction of [N4-(4- acetylamino) benzene sulfonyl) piperazinyl-N1-1-bromopropane with various β-diketones/β-ketoesters 4a-e.All structures of the newly synthesized compounds were elucidated by elemental analysis and spectral studies.The compounds 6a-e have been screened for antimicrobial, antifungal and anthelmintic activity.
