Check Digit Verification of cas no

The CAS Registry Mumber 1257544-68-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,5,4 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1257544-68:
(9*1)+(8*2)+(7*5)+(6*7)+(5*5)+(4*4)+(3*4)+(2*6)+(1*8)=175
175 % 10 = 5
So 1257544-68-5 is a valid CAS Registry Number.

Oxidative cleavage of alkenes using an in situ generated iodonium ion with oxone as a terminal oxidant

Thottumkara, Prem P.,Vinod, Thottumkara K.

, p. 5640 - 5643 (2010)

A facile and operationally convenient catalytic procedure for oxidative cleavage of alkenes is described. In situ formed [hydroxy(4-carboxyphenyl) iodonium]ion, 2, from the oxidation of 4-iodobenzoic acid, 1, has been shown to facilitate the cleavage of a variety of alkenes in presence of Oxone as a co-oxidant. Optimization of the reaction conditions using 1-phenyl-1- cyclohexene, 3, and the competitive oxidative cleavage of different substrates using the optimized conditions has uncovered important mechanistic details of the reaction.
