Check Digit Verification of cas no

The CAS Registry Mumber 1268821-08-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,2 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1268821-08:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*2)+(3*1)+(2*0)+(1*8)=174
174 % 10 = 4
So 1268821-08-4 is a valid CAS Registry Number.

Synthesis and structure-analgesic activity relationships of a novel series of monospirocyclopiperazinium salts (MSPZ)

Lin, Song-Wen,Sun, Qi,Ge, Ze-Mei,Wang, Xin,Ye, Jia,Li, Run-Tao

, p. 940 - 943 (2011/03/21)

A series of monospirocyclopiperazinium salts were designed and synthesized to search for a peripherally-acting analgesic drug with low side effects. Extensive SAR studies revealed that a suitable NR2R3 was critical for the analgesic activity, which might be beneficial to expose the cationic nitrogen to bind to the receptor, and possibly interact with the receptor via π-π interaction. Introduction of substituting group on the N4-phenyl ring could improve the activity, and the best position was the 4-position. Compound 14n showed more potent analgesic activity (63%, 20 μM/kg, sc) and holds promise for development as a mechanically new analgesic drug.
