Check Digit Verification of cas no

The CAS Registry Mumber 1620134-57-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,3 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1620134-57:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*3)+(3*4)+(2*5)+(1*7)=117
117 % 10 = 7
So 1620134-57-7 is a valid CAS Registry Number.

Substituted N -(biphenyl-4′-yl)methyl (R)-2-acetamido-3- methoxypropionamides: Potent anticonvulsants that affect frequency (Use) dependence and slow inactivation of sodium channels

Lee, Hyosung,Park, Ki Duk,Torregrosa, Robert,Yang, Xiao-Fang,Dustrude, Erik T.,Wang, Yuying,Wilson, Sarah M.,Barbosa, Cindy,Xiao, Yucheng,Cummins, Theodore R.,Khanna, Rajesh,Kohn, Harold

, p. 6165 - 6182 (2014)

We prepared 13 derivatives of N-(biphenyl-4′-yl)methyl (R)-2-acetamido-3-methoxypropionamide that differed in type and placement of a R-substituent in the terminal aryl unit. We demonstrated that the R-substituent impacted the compound's whole animal and cellular pharmacological activities. In rodents, select compounds exhibited excellent anticonvulsant activities and protective indices (PI = TD50/ED50) that compared favorably with clinical antiseizure drugs. Compounds with a polar, aprotic R-substituent potently promoted Na+ channel slow inactivation and displayed frequency (use) inhibition of Na+ currents at low micromolar concentrations. The possible advantage of affecting these two pathways to decrease neurological hyperexcitability is discussed.
