Check Digit Verification of cas no
The CAS Registry Mumber 137669-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,6 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137669-05:
(8*1)+(7*3)+(6*7)+(5*6)+(4*6)+(3*9)+(2*0)+(1*5)=157
157 % 10 = 7
So 137669-05-7 is a valid CAS Registry Number.

The Regioselective Cleavage of Aryl Tosylates by Electrochemical Reduction
Civitello, Edgar R.,Rapoport, Henry
, p. 834 - 840 (2007/10/02)
The electrochemical reductions of eight bis(tosyloxy)benzenoid compounds were studied as a method for the regioselective cleavage of aryl tosylates.For the methyl bis(tosyloxy)benzoate isomers, a strong preference was observed for cleavage of the tosyl group in conjugation with the electron-withdrawing ester moiety.Thus it was possible to selectively cleave tosyl groups to the ortho or para positions over tosyl groups at the meta positions.The bis(tosyloxy)anisole isomers displayed the opposite regioselectivity favoring cleavage of tosyl groups that were meta to the electron-donating methoxy substituent.The general electrochemical process for the reduction of aryl tosylates has been shown to be selective, high yielding, and reproducible on gram quantities.
