Check Digit Verification of cas no

The CAS Registry Mumber 19057-38-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,5 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19057-38:
(7*1)+(6*9)+(5*0)+(4*5)+(3*7)+(2*3)+(1*8)=116
116 % 10 = 6
So 19057-38-6 is a valid CAS Registry Number.

13C, 19F and 1H ENDOR Investigations of Substituent Effects on Lifting of Orbital Degeneracy in Cyclopentadienyl Radicals. Syntheses

Kieslich, W.,Kurreck, H.

, p. 4328 - 4335 (2007/10/02)

A variety of substituted, partially deuterated, and 13C-labeled pentaphenylcyclopentadienyl radicals ("Ziegler's radicals") have been synthesized.It is shown from 13C, 19F, and 1H ENDOR experiments that monosubstitution removes the orbital degeneracy of t
