174089-60-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174089-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,0,8 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174089-60:
(8*1)+(7*7)+(6*4)+(5*0)+(4*8)+(3*9)+(2*6)+(1*0)=152
152 % 10 = 2
So 174089-60-2 is a valid CAS Registry Number.

Synthesis and structure of AzAsx-pro-containing Aza-peptides
Andre, Frederic,Marraud, Michel,Boussard, Guy,Didierjean, Claude,Aubry, Andre
, p. 183 - 186 (1996)
One possible α-modification in peptides is the substitution of a nitrogen for the CαH group. We propose triphosgene as a carbonylating agent for coupling the properly substituted hydrazide to the proline nitrogen to obtain the AzAsx-Pro or AzAl
