498573-81-2 Usage
Uses
(S)-(?)-Tetrahydrofuran-2-carboxamide can be used as a precursor for the preparation of (S)-tetrahydrofuran-2-carbonitrile (THFCN) via dehydration reaction using thionyl chloride and DMF. THFCN can be further methylated with methylmagnesium chloride (Grignard reagent) to produce (S)-1-(tetrahydrofuran-2-yl)ethenone.
Check Digit Verification of cas no
The CAS Registry Mumber 498573-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,7 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 498573-81:
(8*4)+(7*9)+(6*8)+(5*5)+(4*7)+(3*3)+(2*8)+(1*1)=222
222 % 10 = 2
So 498573-81-2 is a valid CAS Registry Number.
