The CAS Registry Mumber 917241-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917241-90:
(8*9)+(7*1)+(6*7)+(5*2)+(4*4)+(3*1)+(2*9)+(1*0)=168
168 % 10 = 8
So 917241-90-8 is a valid CAS Registry Number.

Asymmetric synthesis of 2-aryl-5-oxotetrahydrofuran-2-carboxylic acids

Jogi, Artur,Paju, Anne,Pehk, Tonis,Kailas, Tiiu,Mueuerisepp, Aleksander-Mati,Kanger, Tonis,Lopp, Margus

, p. 3031 - 3036 (2006)

3-Aryl-2-hydroxycyclopent-2-en-1-ones, when subjected to asymmetric oxidation, result in enantiomerically enriched 2-aryl-5-oxotetrahydrofuran-2- carboxylic acids. Electron-donating substituents in the para position of the phenyl ring increase the yield and decrease the enantioselectivity of the process. Georg Thieme Verlag Stuttgart.
