Check Digit Verification of cas no

The CAS Registry Mumber 643744-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,4 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 643744-80:
(8*6)+(7*4)+(6*3)+(5*7)+(4*4)+(3*4)+(2*8)+(1*0)=173
173 % 10 = 3
So 643744-80-3 is a valid CAS Registry Number.

A general synthetic route to 1-azabicyclo[m.n.0]alkenes via cyclisation based on α-sulfinyl carbanions was presented. The intramolecular nucleophillic addition of α-sulfinyl carbanions afforded 1-azabicyclo[m.n.0]alkenes in good yields. It is reported that the developed strategy should provide a general solution for the synthesis of various classes of 1-azabicyclic alkaloids.
