110998-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110998-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,9 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 110998-15:
(8*1)+(7*1)+(6*0)+(5*9)+(4*9)+(3*8)+(2*1)+(1*5)=127
127 % 10 = 7
So 110998-15-7 is a valid CAS Registry Number.

Novikov, Pavel V.,Malyshev, Oleg R.,Lyssenko, Konstantin A.,Kostyanovsky, Remir G.
, p. 310 - 312 (2004)
The three-step synthesis of adduct 3 has been reinvestigated; enantiomers 3a and 3b have been separated by enantioselective chromatography and the racemization barrier of 3a was determined as ΔG≠ = 24.4 kcal mol-1 (16 ° C).
