Check Digit Verification of cas no

The CAS Registry Mumber 1389264-93-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,9,2,6 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1389264-93:
(9*1)+(8*3)+(7*8)+(6*9)+(5*2)+(4*6)+(3*4)+(2*9)+(1*3)=210
210 % 10 = 0
So 1389264-93-0 is a valid CAS Registry Number.

TEMPO-mediated oxidation of alcohols with ion-supported (diacetoxyiodo)benzenes

Suzuki, Yusuke,Iinuma, Masataka,Moriyama, Katsuhiko,Togo, Hideo

, p. 1250 - 1256 (2012)

The oxidation of secondary alcohols and primary alcohols with novel ion-supported (diacetoxyiodo)benzenes (IS-DIB) in the presence of a catalytic amount of 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) in dichloromethane at room temperature proceeded efficiently to provide the corresponding ketones and aldehydes, respectively, in good yields with high purity. Isolation of the product was easily accomplished by simple diethyl ether extraction of the reaction mixture and subsequent removal of the solvent from the extract. Moreover, ion-supported iodobenzenes, which were co-products derived from IS-DIB in the present oxidation, were recovered in good yields and could be re-oxidized to IS-DIB for reuse in the same oxidation.
