Check Digit Verification of cas no

The CAS Registry Mumber 84438-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84438-40:
(7*8)+(6*4)+(5*4)+(4*3)+(3*8)+(2*4)+(1*0)=144
144 % 10 = 4
So 84438-40-4 is a valid CAS Registry Number.

REACTIONS OF 10-TELLURONIAANTHRACENE PERCHLORATES WITH NUCLEOPHILES

Ladatko, A. A.,Sadekov, I. D.,Etmetchenko, L. N.,Minkin, V. I.

, p. 577 - 580 (2007/10/02)

10-Telluroniaanthracene perchlorates react with nucleophiles (X(-)= halide, hydroxide, methoxide) via intermediate free telluroxanthyl radicals.With 9-aryl-10-telluroniaanthracene perchlorates, high yields of 9-aryl-9-X-telluroxanthenes are obtained, but with 10-telluroniaanthracene the principal product is 9,9'-bis(telluroxathenyl) as a result of rapid competitive dimerization.
