220220-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220220-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220220-55:
(8*2)+(7*2)+(6*0)+(5*2)+(4*2)+(3*0)+(2*5)+(1*5)=63
63 % 10 = 3
So 220220-55-3 is a valid CAS Registry Number.

Construction of 3,4-disubstituted tetrahydrofuran ring by radical cyclization. A model study for kainoid synthesis
Itadani, Satoshi,Hashimoto, Kimiko,Shirahama, Haruhisa
, p. 105 - 108 (2007/10/03)
Radical cyclization for construction of the 3,4-disubstituted tetrahydrofuran ring was attempted. The radical was produced through a charge-transfer complex under irradiation conditions.
