Check Digit Verification of cas no
The CAS Registry Mumber 139013-68-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,1 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139013-68:
(8*1)+(7*3)+(6*9)+(5*0)+(4*1)+(3*3)+(2*6)+(1*8)=116
116 % 10 = 6
So 139013-68-6 is a valid CAS Registry Number.

PROCESS FOR THE EFFICIENT PREPARATION OF 3-HYDROXYTETRAHYDROFURAN
-
Paragraph 89-90, (2008/12/07)
Disclosed is a process for the efficient preparation of 3-hydroxytetrahydrofuran. In particular, the present invention provides a process for the preparation of 3-hydroxytetrahydrofuran by performing cyclization of 4-halo-1,3-butanediol either neat or in an organic solvent by heating to 75°C to 18O°C. In the present invention, acidic solution is not used in the cyclization and, thus, the reaction environment is improved. Further, the cyclization product 3-hydroxytetrahydrofuran is purified by a simple process. In addition, according to the present invention, chirality of the starting material is substantially maintained. Consequently, chiral 3-hydroxytetrahydrofuran with a high optical purity of 99.0% ee or better can be prepared economically, in high yield.
