Check Digit Verification of cas no

The CAS Registry Mumber 138240-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138240-07:
(8*1)+(7*3)+(6*8)+(5*2)+(4*4)+(3*0)+(2*0)+(1*7)=110
110 % 10 = 0
So 138240-07-0 is a valid CAS Registry Number.

Aerobic Oxygenation of Olefinic Compounds into the Corresponding α-Hydroxy Ketones Using the Catalyst System of OsO4 and Ni(II) Complex

Takai, Toshihiro,Yamada, Tohru,Mukaiyama, Teruaki

, p. 1499 - 1502 (1991)

In the presence of the catalyst system of OsO4 and bis(3-methyl-2,4-pentanedionato)nickel(II), various olefinic compounds are directly converted into the corresponding α-hydroxy ketones in good yields with molecular oxygen and an aldehyde.

Regiochemistry of Boron Trifluoride Mediated Hydrolysis of Glycidyl Benzoates

Yoshitake, Makoto,Kobayashi, Hiroyuki,Yamamoto, Makoto,Kohmoto, Shigeo,Yamada, Kazutoshi

, p. 1865 - 1868 (2007/10/02)

Hydrolysis of glycidyl benzoates in the presence of BF3*OEt2 in CH2Cl2 affords regioisomeric triol monobenzoates, their ratios remarkably change depending on the temperature particularly in the reaction of 3,3-dimethylglycidyl benzoate.
