Check Digit Verification of cas no

The CAS Registry Mumber 77153-29-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,5 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77153-29:
(7*7)+(6*7)+(5*1)+(4*5)+(3*3)+(2*2)+(1*9)=138
138 % 10 = 8
So 77153-29-8 is a valid CAS Registry Number.

Kinetic Study of the Homolytic Brominolysis of 1,2-Diarylcyclopropanes

Applequist, Douglas E.,Gdanski, Rick D.

, p. 2502 - 2510 (2007/10/02)

The rate constants for the photolytic brominolysis of 22 trans-1,2-diarylcyclopropanes in carbon disulfide relative to an internal standard, p-chlorotoluene, have been determined.The products of the brominolysis are 1,3-dibromo-1,3-diarylpropanes.The rate constants range over 5 orders of magnitude, being enhanced by electrondonating substituents on one or both benzene rings.The quantitative size of the substituent effect (ρ) at either involved carbon center is a function of the substituent at the other center.This fact suggests a continuum of transition-state structures with varying degrees of bond breaking and charge separation.
