133125-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133125-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,2 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133125-33:
(8*1)+(7*3)+(6*3)+(5*1)+(4*2)+(3*5)+(2*3)+(1*3)=84
84 % 10 = 4
So 133125-33-4 is a valid CAS Registry Number.

PROTECTION DES ACIDES PAR LES GROUPEMENTS ABz. UTILISATION EN SYNTHESE PEPTIDIQUE
Loubinoux, Bernard,Gerardin, Philippe
, p. 239 - 248 (2007/10/02)
The novel azidomethoxybenzyl esters (ABz esters) of various acids are easily obtained and are cleanly cleaved in very mild reductive conditions.Such esters serve to protect the carboxyl group in peptide synthesis without any racemisation.
