Check Digit Verification of cas no

The CAS Registry Mumber 77529-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,2 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77529-58:
(7*7)+(6*7)+(5*5)+(4*2)+(3*9)+(2*5)+(1*8)=169
169 % 10 = 9
So 77529-58-9 is a valid CAS Registry Number.

REACTIONS OF PERFLUOROALKYL IODIDES WITH PHOSPHORUS(III) ESTERS. KINETICS AND MECHANISM OF THE REACTIONS OF HEPTAFLUOROPROPYL IODIDE WITH ETHYLPHOPHONOUS ESTERS

Garabadzhiu, A. V.,Ivanov, S. A.,Lavrent'ev, A. N.,Shibaev, V. I.

, p. 1905 - 1910 (2007/10/02)

1.The kinetics of the fluoroalkylation of ethylphosphonous esters were studied, and it was shown that for the reaction low values of effective activation energy are characteristic. 2.In the first stage of the reactions of phosphonous esters with heptafluoropropyl iodide the formation of donor-acceptor complexes ocurs. 3.The rate-determining stage of the complex process is the stage of the formation of the intermediate compound.
