Check Digit Verification of cas no
The CAS Registry Mumber 133525-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,2 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133525-05:
(8*1)+(7*3)+(6*3)+(5*5)+(4*2)+(3*5)+(2*0)+(1*5)=100
100 % 10 = 0
So 133525-05-0 is a valid CAS Registry Number.

, p. 693 - 696 (2007/10/02)
A method has been developed for the synthesis of methyl piperazinium-2-carboxylate dihydrochloride (overall yield 46percent) and piperazinium-2-carboxylic acid dihydrochloride (overall yield 36percent), from ethylene diamine through N,N'-di(trifluoroacetyl)ethylenediamine and methyl N,N'-di(trifluoroacetyl)piperazine-2-carboxylate.The N,N'-dinitroso derivatives were synthesized.
