The CAS Registry Mumber 1304143-77-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,1,4 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1304143-77:
(9*1)+(8*3)+(7*0)+(6*4)+(5*1)+(4*4)+(3*3)+(2*7)+(1*7)=108

PROCESS FOR PREPARING CREATINE AMIDES

-

Page/Page column 3, (2012/11/08)

The invention relates to the field of pharmaceutical chemistry, specifically to processes for preparing biologically active substances (BAS), in particular creatine amides. What is proposed is a process for preparing creatine amides which comprises treating creatine with para-toluenesulfonic acid in an organic solvent with subsequent reaction of the resultant complex with compounds comprising a primary or secondary amino group in the presence of a condensing agent and a base which are introduced subsequently. The claimed process makes it possible to increase the yield of the end product by 2-5 times in comparison with analogs and also to extend the range of the compounds prepared.
