Check Digit Verification of cas no

The CAS Registry Mumber 213014-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,0,1 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 213014-92:
(8*2)+(7*1)+(6*3)+(5*0)+(4*1)+(3*4)+(2*9)+(1*2)=77
77 % 10 = 7
So 213014-92-7 is a valid CAS Registry Number.

, p. 5979 - 5982 (2007/10/03)

A series of 1,1'(2,4-di-X-benzene-1,3-diyl)bis[1-(4-Y-phenyl)-2- picrylhydrazine]s were prepared an oxidized to generate the corresponding bis-DPPH diradicals. No triplet species was observed for the compounds with X = H in the ESR measurement. Modification of the central benzene ring (x = Me) and N-phenyl group (Y = OMe, P, t-Bu) allowed the detection of their triplet diradicals. Especially, the diradical with X = Me, Y = t-Bu was successfully purified, isolated at O aC as a purple solid, and was shown to be in a triplet ground state.
