Check Digit Verification of cas no
The CAS Registry Mumber 6443-72-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6443-72:
(6*6)+(5*4)+(4*4)+(3*3)+(2*7)+(1*2)=97
97 % 10 = 7
So 6443-72-7 is a valid CAS Registry Number.

Oxidative coupling using molybdenum(V) reagents provides fast access to highly functionalized 9-monosubstituted fluorenes. This synthetic approach is highly modular, is high yielding, and tolerates a variety of labile moieties, e.g. amides or iodo groups. The established protocol leads to promising precursors for pharmacologically important analogues of melatonin.
