134558-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134558-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134558-09:
(8*1)+(7*3)+(6*4)+(5*5)+(4*5)+(3*8)+(2*0)+(1*9)=131
131 % 10 = 1
So 134558-09-1 is a valid CAS Registry Number.

Synthesis of an α-CH2CO2H functionalized tryptophan and its incorporation into an analogue of cholecystokinin
Bourne,Horwell,Pritchard
, p. 4763 - 4774 (1991)
The synthesis of an α, α-bisubstituted tryptophan derivative (2) predicted by computer assisted molecular modelling to have close structural and conformational analogy to the endogenous neuropeptide cholecystokinin (CCK) is described. Central to the synth
