Check Digit Verification of cas no

The CAS Registry Mumber 109752-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,5 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109752-09:
(8*1)+(7*0)+(6*9)+(5*7)+(4*5)+(3*2)+(2*0)+(1*9)=132
132 % 10 = 2
So 109752-09-2 is a valid CAS Registry Number.

A Simple and Improved Procedure for the Conversion of Alkynes to 1,2-Diketones by Indirect Electrooxidation With Ruthenium Tetroxide as a Mediator

Torii, Sigeru,Inokuchi, Tsutomu,Hirata, Youzou

, p. 377 - 379 (2007/10/02)

Indirect electrooxidation of alkynes 1 using ruthenium tetroxide as a mediator, leading to 1,2-diones 2 in 72-87percent, is described.The electrolysis is carried out in the presence of a catalytic amount of ruthenium dioxide dihydrate in a two phase system of saturated aqueous sodium chloride and carbon tetrachloride.The overoxidation of 1,2-diones to the corresponding carboxylic acid, an unavoidable drawback generally encountered in the metal oxidation of acetylenes, is suppressed greatly by maintaining the pH of the aqueous phase at 4 and conducting the reaction at 0-5 deg C.The synthetic utility of this electrochemical oxidation is exemplified by the preparation of 2i (82percent), a key intermediate for the synthesis of furaneol 4, from the commercially available 1i.
