Check Digit Verification of cas no

The CAS Registry Mumber 28951-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,5 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28951-67:
(7*2)+(6*8)+(5*9)+(4*5)+(3*1)+(2*6)+(1*7)=149
149 % 10 = 9
So 28951-67-9 is a valid CAS Registry Number.

The preparation of bis(trifluoromethyl)-1,2-diselenetene and some 1,2-diselenolene transition metal complexes

Davison,Shawl

, p. 1820 - 1825 (2007/10/06)

The synthesis and properties of the heterocycle Se2C2(CF3)2 are described. Various attempts to prepare related compounds formally derived from ethylene-1,2-diselenol are discussed. The preparation and properties of a representative series of bis(trifluoromethyl)-1,2-diselenetene transition metal complexes are reported. The complexes are similar in behavior to the corresponding dithiolene species, though they are much less stable.
