93709-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93709-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,0 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93709-68:
(7*9)+(6*3)+(5*7)+(4*0)+(3*9)+(2*6)+(1*8)=163
163 % 10 = 3
So 93709-68-3 is a valid CAS Registry Number.

N-TERMINAL SUBSTITUENT AND SIDE-CHAIN INFLUENCES ON THE CHEMICAL SHIFTS OF PROTONS IN MODEL DIPEPTIDE SYSTEMS
Davies, John S.,Hakeem, Essam
, p. 1387 - 1392 (2007/10/02)
(1)H Chemical shift values of ester methyls in model dipeptide esters have been shown to be sensitive to (a) the nature and configuration of the constituent amino acids and (b) the spatial distance between the N-terminal aryl group and the ester protons.C
