514-68-1 Usage
Originator
Hemostyptanon,Endopancrine,France,1966
Uses
Estrogen.
Manufacturing Process
Succinic anhydride and 60 ml of pyridine is heated at 90°C for 4 hours, after which the reaction
mixture is poured into water. The aqueous solution is extracted with ether, the
ether layer is separated, washed with diluted sulfuric acid and after that with
water until neutral, then evaporated to dryness to obtain 14 grams of an
amorphous substance. Melting point 82° to 86°C. This drying residue proves
to consist of a mixture of estriol disuccinate and estriol monosuccinate, which
are separated by repeated crystallization from a mixture of methanol and
water.
Therapeutic Function
Estrogen
Check Digit Verification of cas no
The CAS Registry Mumber 514-68-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 514-68:
(5*5)+(4*1)+(3*4)+(2*6)+(1*8)=61
61 % 10 = 1
So 514-68-1 is a valid CAS Registry Number.
