Check Digit Verification of cas no

The CAS Registry Mumber 201743-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,4 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 201743-97:
(8*2)+(7*0)+(6*1)+(5*7)+(4*4)+(3*3)+(2*9)+(1*7)=107
107 % 10 = 7
So 201743-97-7 is a valid CAS Registry Number.

Intramolecular photocyclisation reactions of 5-tert-butyldimethylsilyloxymethyl-3-(3-formylpropyl)furan-2(5H)-one: Formation of bicyclic and spirobicyclic lactones

Brown, David,Drew, Michael G. B.,Mann, John

, p. 3651 - 3655 (2007/10/03)

5-tert-Butyldimethylsilyloxymethyl-3-(3-formylpropyl)furan-2(5H)-one has been synthesised and upon irradiation yields either one homochiral bicyclic lactone or a mixture of spirobicyclic lactones (in modest yield) depending upon the irradiation conditions.
