Check Digit Verification of cas no

The CAS Registry Mumber 18448-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,4 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18448-45:
(7*1)+(6*8)+(5*4)+(4*4)+(3*8)+(2*4)+(1*5)=128
128 % 10 = 8
So 18448-45-8 is a valid CAS Registry Number.

Metal-free TEMPO-catalyzed oxidative C-C bond formation from Csp 3-H bonds using molecular oxygen as the oxidant

Zhang, Bo,Cui, Yuxin,Jiao, Ning

supporting information; scheme or table, p. 4498 - 4500 (2012/06/01)

An efficient TEMPO-catalyzed oxidative C-C bond formation with two Csp 3-H bonds using molecular oxygen as the oxidant has been developed. The novel transformation provides a new strategy for the TEMPO-O2 catalysis to construct C-C bonds. The advantages of this method include: (1) relatively mild and neutral conditions; (2) simplicity and safety of operation; (3) a stoichiometric amount of dangerous oxidants, any transition metals, additives, even solvent, is not required.
