Check Digit Verification of cas no

The CAS Registry Mumber 1161920-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,9,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1161920-75:
(9*1)+(8*1)+(7*6)+(6*1)+(5*9)+(4*2)+(3*0)+(2*7)+(1*5)=137
137 % 10 = 7
So 1161920-75-7 is a valid CAS Registry Number.

Optically active 4-amino-4-aryl-5,5,5-trifluoropentan-2-ones: Versatile reagents for synthesis of chiral 4-trifluoromethyl-3,4-dihydroazin-2-ones

Sukach, Volodymyr A.,Golovach, Nataliya M.,Melnichenko, Nina V.,Tsymbal, Ivan F.,Vovk, Mykhaylo V.

experimental part, p. 1180 - 1186 (2009/04/07)

A cyclocondensation of disubstituted (thio)ureas and isocyanates derived from enantiomerically enriched 4-amino-4-aryl-5,5,5-trifluoropentan-2-ones affords a novel synthetic access to chiral 4-trifluoromethyl-substituted 3,4-dihydropyrimidin-2(1H)-(thi)ones and 3,4-dihydro-1,3-oxazin-2-ones, respectively.
