309729-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 309729-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,7,2 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 309729-41:
(8*3)+(7*0)+(6*9)+(5*7)+(4*2)+(3*9)+(2*4)+(1*1)=157
157 % 10 = 7
So 309729-41-7 is a valid CAS Registry Number.

Synthesis and evaluation of n,n-dialkyl enkephalin-based affinity labels for δ opioid receptors
Maeda,Ishmael,Murray,Aldrich
, p. 3941 - 3948 (2007/10/03)
To develop affinity labels for δ opioid receptors based on peptide antagonists, the Phe4 residues of N,N-dibenzylleucine enkephalin and N,N-diallyl[Aib2,Aib3]leucine enkephalin (ICI-174,864) were substituted with either Ph
