Check Digit Verification of cas no

The CAS Registry Mumber 139925-07-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,2 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139925-07:
(8*1)+(7*3)+(6*9)+(5*9)+(4*2)+(3*5)+(2*0)+(1*7)=158
158 % 10 = 8
So 139925-07-8 is a valid CAS Registry Number.

Synthesis and Spectroscopic Properties of Chiral 1,3-Oxazolidines

Evers, R.,Michalik, M.

, p. 699 - 710 (2007/10/02)

(1S,2S)-2-Amino-1-(p-nitrophenyl)-propane-1,3-diol 2a and the (1R,2R)-configurated isomer 2b react with N-substituted dithiocarbimidic acid diesters and ketenedithioacetals, respectively, to give the 2-substituted chiral 4-hydroxymethyl-5-phenyl-1,3-oxazolidines 4 and 7.N-Carbomethoxy-dithiocarbimidic acid dimethylester yields under the same conditions the isomeric 1,3-oxazolidine 5.On treatment of 4 and 7 with isocyanates crystalline urethanes 9 are formed.
