109638-48-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109638-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,3 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109638-48:
(8*1)+(7*0)+(6*9)+(5*6)+(4*3)+(3*8)+(2*4)+(1*8)=144
144 % 10 = 4
So 109638-48-4 is a valid CAS Registry Number.

Copper-catalyzed oxidative desulfurization-oxygenation of thiocarbonyl compounds using molecular oxygen: An efficient method for the preparation of oxygen isotopically labeled carbonyl compounds

Shibahara, Fumitoshi,Suenami, Aiko,Yoshida, Atsunori,Murai, Toshiaki

, p. 2354 - 2356 (2007)

A novel copper-catalyzed oxidative desulfurization reaction of thiocarbonyl compounds, using molecular oxygen as an oxidant and leading to formation of carbonyl compounds, has been developed, and the utility of the process is demonstrated by its application to the preparation of a carbonyl-18O labeled sialic acid derivative.
