18922-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18922-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18922-13:
(7*1)+(6*8)+(5*9)+(4*2)+(3*2)+(2*1)+(1*3)=119
119 % 10 = 9
So 18922-13-9 is a valid CAS Registry Number.

Optically Active trans-Diethylstilbesterol Oxide Monomethyl Ether

Oda, Taiko,Watanuki, Mitsuru,Sato, Yoshihiro,Hata, Tadashi

, p. 810 - 815 (2007/10/02)

Diethylstilbestrol oxide is a metabolic intermediate of diethylstilbestrol.In order to elucidate the effects of optically active diethylstilbestrol oxides on microtubule assembly and cell culture, we synthesized (+/-)-diethylstilbestrol oxide (2a).Since 2a was not stable under moderately acidic and basic conditions, the monomethyl ether (2c) of diethylstilbestrol oxide, which was more stable than 2a, was separated by high-pressure liquid chromatography using a chiral column.The mono (4-bromobenzoate) of (-)-2c was analyzed by X-ray crystallography and its absolute structure was determined as C (1R,1'R).Keywords: optical resolution; diethylstilbestrol oxide monomethyl ether; absolute structure; X-ray crystallography; pig liver esterase; diethylstilbestrol oxide
