Check Digit Verification of cas no
The CAS Registry Mumber 681-58-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 681-58:
(5*6)+(4*8)+(3*1)+(2*5)+(1*8)=83
83 % 10 = 3
So 681-58-3 is a valid CAS Registry Number.

REACTION OF TETRAKIS(POLYFLUOROALKOXY)TELLURANES WITH CARBOXYLIC AND DICARBOXYLIC ACID ANHYDRIDES
Stukalo, E. A.,Yur'eva, E. M.,Markovskii, L. N.

Depending on the reaction conditions, the reaction of tetrakis(polyfluoroalkoxy)telluranes with acetic, trifluoroacetic, benzoic, and phthalic anhydrides gives acyloxy(polyfluoroalkoxy)telluranes or esters of acyloxytellurous acid, which are a new type of derivatives of tetra- and hexacoordinated tellurium.Polyfluorinated esters are also obtained in the reaction of acid anhydrides with (polyfluoroalkoxy)telluranes.
