Check Digit Verification of cas no

The CAS Registry Mumber 164934-46-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,9,3 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 164934-46:
(8*1)+(7*6)+(6*4)+(5*9)+(4*3)+(3*4)+(2*4)+(1*6)=157
157 % 10 = 7
So 164934-46-7 is a valid CAS Registry Number.

Cholinergic Agents. Synthesis and Acetylcholinesterase Inhibitory Activity of Some ω-[N-Methyl-N-(3-alkylcarbamoyloxyphenyl)methyl]aminoalkoxyxanthen-9-ones

Valentini, Piero,Rampa, Angela,Bisi, Alessandra,Fabbri, Giuseppina,Andrisano, Vincenza,Cavrini, Vanni

, p. 255 - 264 (2007/10/03)

A series of ω-[N-methyl-N-(3-alkylcarbamoyloxyphenyl)methyl]aminoalkoxyxanthen-9-ones was prepared. The alkoxy chain occupies, alternatively, the positions 2, 3 and 4 of the xanthone moiety and has a variable length. The compounds were evaluated for acetylcholinesterase inhibitory activity. Some in this series were revealed to be more potent than physostigmine. Optimum activity was found with the 3 position and with a four or three carbon chain length separating the benzylamino group from the xanthenonyloxy moiety.
