157630-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157630-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,3 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157630-07:
(8*1)+(7*5)+(6*7)+(5*6)+(4*3)+(3*0)+(2*0)+(1*7)=134
134 % 10 = 4
So 157630-07-4 is a valid CAS Registry Number.

PROCESS FOR PREPARING EPTIFIBATIDE
-
Page/Page column, (2014/06/24)
The present invention provides processes for preparation of eptifibatide that involve coupling of amino acids in a (2+5), (4+3) and (3+4) sequence method. The invention further provides products produced by the described processes, novel compounds that can be used as synthetic intermediates for the preparation of eptifibatide.
