1332726-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1332726-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,2,7,2 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1332726-71:
(9*1)+(8*3)+(7*3)+(6*2)+(5*7)+(4*2)+(3*6)+(2*7)+(1*1)=142
142 % 10 = 2
So 1332726-71-2 is a valid CAS Registry Number.

Synthesis of an enkephalin analogue containing an α,α- disubstituted heterocyclic aminophosphonic acid
Rabasso, Nicolas,Fadel, Antoine
, p. 1811 - 1819 (2011/10/08)
Synthesis of a phosphonopentapeptide enkephalin analogue was achieved from heterocyclic aminophosphonates via the coupling of Boc-Tyr-Gly-Gly-OH with phosphonodipeptide. The latter was formed by coupling Boc-Phe-OH with N-terminal α,α-disubstituted hetero
