Check Digit Verification of cas no

The CAS Registry Mumber 162307-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,3,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 162307-17:
(8*1)+(7*6)+(6*2)+(5*3)+(4*0)+(3*7)+(2*1)+(1*7)=107
107 % 10 = 7
So 162307-17-7 is a valid CAS Registry Number.

Addition of molecular fluorine to 2-azabicyclo[2.2.1]hept-5-en-3-one and related compounds: Synthesis of difluorinated carbocyclic nucleosides

, p. 8783 - 8798 (2007/10/02)

Addition of molecular fluorine to bicyclo[2.2.1]hept-2-ene derivatives having electronegative substituent(s) on the ethano bridge has been found to give exo,exo-difluoro adducts with high stereoselectivity. The difluoro adducts derived from 2-azabicyclo[2.2.1]hept-5-en-3-ones having an electron-withdrawing group at 2-position were converted to the difluorinated carbocyclic nucleoside analogs.
