Check Digit Verification of cas no

The CAS Registry Mumber 1620401-54-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,4,0 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1620401-54:
(9*1)+(8*6)+(7*2)+(6*0)+(5*4)+(4*0)+(3*1)+(2*5)+(1*4)=108
108 % 10 = 8
So 1620401-54-8 is a valid CAS Registry Number.

ISOMETHEPTENE ISOMER

-

, (2014/08/07)

The invention relates to a purified Isometheptene compound comprising the structure according to Formula (I), or a hydrochloride, or a pharmaceutically acceptable addition salt thereof. In particular, the disclosure relates to the synthesis, purification and characterization of an Isometheptene isomer mucate crystal 2, wherein the Isometheptene isomer 2 is stereochemically characterized as (R)-enantiomer, respectively. The Isometheptene (R)-enantiomer activity indicates a selective centrally acting selective ligand for Imidazoline subtype 1 (I1) receptor sites; and more specifically, the disclosure provides an antihypertensive composition for treatment of migraine and other neurovascular or neurogenic pain from abdominal distress. (R)-Isometheptene enantiomer or isomer 2 may be an anti-hypertensive agent with lower side effects than the racemate form. Therefore (R)-Isometheptene is believed to be effective against episodic tension-type headaches (ETTH). The (R)-Isometheptene enantiomer or isomer 2 is believed to effectively lower blood pressure, used alone or together with other headache ameliorating drugs. Methods of synthesis and treatment are described. Regarding (R)-Isometheptene crystals data of X-ray crystallography are presented.
