Check Digit Verification of cas no
The CAS Registry Mumber 124962-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,6 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124962-12:
(8*1)+(7*2)+(6*4)+(5*9)+(4*6)+(3*2)+(2*1)+(1*2)=125
125 % 10 = 5
So 124962-12-5 is a valid CAS Registry Number.

A two-step mimic for direct, asymmetric bromonium- and chloronium-induced polyene cyclizations
Snyder, Scott A.,Treitler, Daniel S.,Schall, Andreas
experimental part, p. 4796 - 4804 (2010/08/07)
Although direct, asymmetric, halonium-induced cyclizations have proven difficult to achieve in the absence of enzymes, this report provides a two-step alternative based on reacting polyenes with chiral mercury(II) complexes to afford a number of polycyclic organomercurials that can be subsequently converted, with retention, into their corresponding chlorine, bromine, and iodine derivatives in good yield and enantioselectivity. A five-step asymmetric total synthesis of the natural product 4-isocymobarbatol is also described.
