478070-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478070-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,0,7 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 478070-16:
(8*4)+(7*7)+(6*8)+(5*0)+(4*7)+(3*0)+(2*1)+(1*6)=165
165 % 10 = 5
So 478070-16-5 is a valid CAS Registry Number.

Upon treatment with CF3COOH at 70°C, trisubstituted-tetrahydropyrans, which were stereoselectively prepared from δ-lactones, were found to be converted into the corresponding 2,5-disubstituted-tetrahydrofurans stereospecifically via a phenonium
