23519-26-8 Usage

Originator

Stilphostrol,Dome,US,1955

Uses

Estrogen.

Manufacturing Process

A solution of 1 part of α,α'-diethyl-4,4'-dihydroxystilbene in 5 parts of pyridine is added drop by drop to the strongly cooled solution of 2 parts of phosphorus-hydroxy chloride in 5 parts of pyridine. The mixture soon solidifies to a crystalline magma. It is allowed to stand in ice for ? hour and then for an hour at room temperature. The mass is then poured into an excess of saturated sodium bicarbonate solution. Unconsumed parent material is removed by extraction with ether. The aqueous solution is then mixed with 2 N hydrochloric acid, whereupon the primary phosphoric acid ester of α,α'- diethyl-4,4'-dihydroxystilbene of the formula is precipitated in the form of a voluminous white powder. By recrystallization or reprecipitation this ester may be further purified.

Therapeutic Function

Estrogen, Antitumor

Check Digit Verification of cas no

The CAS Registry Mumber 23519-26-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,1 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23519-26:
(7*2)+(6*3)+(5*5)+(4*1)+(3*9)+(2*2)+(1*6)=98
98 % 10 = 8
So 23519-26-8 is a valid CAS Registry Number.
