142597-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142597-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,9 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142597-25:
(8*1)+(7*4)+(6*2)+(5*5)+(4*9)+(3*7)+(2*2)+(1*5)=139
139 % 10 = 9
So 142597-25-9 is a valid CAS Registry Number.

Synthesis and hydrolysis of dipeptide isosteres containing a proline analogue with latent reactivity
Abell, Andrew D.,Christopher Litten
, p. 3005 - 3008 (2007/10/02)
The N-acyl hydroxymethylpyrrole amino acid analogues 5-7 and 9 were synthesized via a mild DMAP catalysed acylation of pyrrole-2-carboxaldehyde with an acid chloride followed by formyl group reduction with Zn(BH4)2. The N-acyl substi
