565233-07-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 565233-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,5,2,3 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 565233-07:
(8*5)+(7*6)+(6*5)+(5*2)+(4*3)+(3*3)+(2*0)+(1*7)=150
150 % 10 = 0
So 565233-07-0 is a valid CAS Registry Number.

TELLURIUM IN ORGANIC SYNTHESIS X. SYNTHESIS OF 3-HALOGENOBENZOTELLUROPHENE DERIVATIVES
Bergman, Jan,Engman, Lars
, p. 377 - 387 (1980)
Several substituted 3-halogenobenzotellurophenes have been synthesized by treating phenylacetylenes with TeO2 in acetic acid in the presence of a lithium halide.A mechanism is postulated involving an electrophilic attack by a solubilized tellurium spec
