Check Digit Verification of cas no
The CAS Registry Mumber 1961-98-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1961-98:
(6*1)+(5*9)+(4*6)+(3*1)+(2*9)+(1*8)=104
104 % 10 = 4
So 1961-98-4 is a valid CAS Registry Number.

Formation and synthetic utility of benzyl- and phenyl-cyclopentadienylthallium
Singh, Poonam,Rausch, Marvin D.,Bitterwolf, Thomas E.
, p. 273 - 282 (2007/10/02)
Benzyl- and phenyl-cyclopentadiene have been shown to react with thallium ethoxide in ethanol to give the corresponding benzyl- and phenyl-cyclopentadienylthallium compounds in excellent yield.These reagents are air stable for brief periods, have extended shelf-lives, and have been shown to be superior starting materials for the synthesis of a variety of cyclopentadienylmetal complexes.
