Check Digit Verification of cas no
The CAS Registry Mumber 2044-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,4 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2044-21:
(6*2)+(5*0)+(4*4)+(3*4)+(2*2)+(1*1)=45
45 % 10 = 5
So 2044-21-5 is a valid CAS Registry Number.

PRODUCTION OF AMINES
-
Page/Page column 26, (2008/06/13)
A process for the hydrogenation of carboxylic acids and/or derivatives, particularly amides, is described. The process includes reacting an acid or derivative such as an amide with a source of hydrogen in the presence of a catalyst system. The catalyst system obtainable by combining: (a) a source of ruthenium, and (b) a phosphine compound of general Formula I: (Formula I). The hydrogenation reaction is carried out in the presence of a low concentration of water or at low pressure or in the presence of a source of ammonia or the hydrogenation reaction is carried out in the absence of water or a combination of these factors is utilised. The invention also relates to the use of ammonia in the production of primary amines by hydrogenation of carboxylic acids and/or derivatives thereof or a process for the production of primary amines generally.

Amides can be hydrogenated to amines using a catalyst prepared in situ from [Ru(acac)3] and 1,1,1-tris(diphenylphosphinomethyl)ethane; water is required to stabilize the catalyst and primary amines can only be formed (selectivity up to 85%) if ammonia is also present.
