Check Digit Verification of cas no
The CAS Registry Mumber 42743-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42743-23:
(7*4)+(6*2)+(5*7)+(4*4)+(3*3)+(2*2)+(1*3)=107
107 % 10 = 7
So 42743-23-7 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF CARBOPROST AND ITS TROMETHAMINE SALT
-
Page/Page column 12, (2017/06/24)
The subject of the invention is a novel process for the preparation of Carboprost tromethamine salt where alkylation the enone of the general formula (II) is carried out in the presence of a chiral auxiliary in aprotic solvent with a Grignard reagent. The methyl ester epimers of formula (VII) are separated by gravity silicagel chromatography and the salt formation is carried out by using solid tromethamine base.
