Check Digit Verification of cas no
The CAS Registry Mumber 23449-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,4 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23449-67:
(7*2)+(6*3)+(5*4)+(4*4)+(3*9)+(2*6)+(1*7)=114
114 % 10 = 4
So 23449-67-4 is a valid CAS Registry Number.

Polyfunctional tetrahydropyrido[2,3-b]pyrazine scaffolds can be synthesized by sequential reaction of pentafluoropyridine with sodium phenylsulfinate and an appropriate diamine. The polyfunctionality possessed by the difluorinated tetrahydropyrido[2,3-b]pyrazine scaffolds was demonstrated in selected model reactions with nucleophiles to give access to various polysubstituted [6,6]-ring fused systems.
