133941-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133941-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,4 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133941-43:
(8*1)+(7*3)+(6*3)+(5*9)+(4*4)+(3*1)+(2*4)+(1*3)=122
122 % 10 = 2
So 133941-43-2 is a valid CAS Registry Number.

C10 N-Acyl modified KY-506: A possible hybrid analogue of the transition state of peptidyl-prolyl cis-trans isomerization
Donald,Cooper,Furber,Wells,Hutchinson,Black
, p. 1375 - 1378 (1991)
Three C 10 N-Acyl derivatives of FK-506 have been prepared. The reduced receptor binding of these analogues is not consistent with a direct overlap of FK-506 and a peptide substrate.
