166974-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166974-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,9,7 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 166974-22:
(8*1)+(7*6)+(6*6)+(5*9)+(4*7)+(3*4)+(2*2)+(1*2)=177
177 % 10 = 7
So 166974-22-7 is a valid CAS Registry Number.

Unusual synthesis of new glycine antagonists via sequential aldol condensation-lactonization-elimination reaction
Giacobbe, Simone A.,Baraldi, Davide,Di Fabio, Romano
, p. 1689 - 1692 (2007/10/03)
Compounds 2 and 3 were designed in order to probe the North-East region of the strichnine-insensitive glycine binding site of the NMDA receptor. The two products were obtained readily by a tandem aldol condensation- lactonization-elimination step which af
