Check Digit Verification of cas no
The CAS Registry Mumber 117-09-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117-09:
(5*1)+(4*1)+(3*7)+(2*0)+(1*9)=39
39 % 10 = 9
So 117-09-9 is a valid CAS Registry Number.

Process for the preparation of 1-acylamino-5(8)-chloroanthraquinones

, (2008/06/13)
The invention relates to a novel process for the preparation of 1-acylamino-5(8)-chloroanthraquinones, which are starting materials for the preparation of vat dyes. It is characterized in that 1,5(8)-dichloroanthraquinones is reacted with ammonia at temperatures of 190° to 240° C., the amino groups in the reaction mixture are completely acylated and the more sparingly soluble diacylaminoanthraquinone is separated off from the more readily soluble monoacylaminochloroanthraquinone. The new process yields reaction products which are purer and cheaper than those which are obtained by conventional methods. Moreover there are smaller waste water problems.
