138228-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138228-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,2 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138228-38:
(8*1)+(7*3)+(6*8)+(5*2)+(4*2)+(3*8)+(2*3)+(1*8)=133
133 % 10 = 3
So 138228-38-3 is a valid CAS Registry Number.

Studies on analgesic oligopeptides. VII. Solid phase synthesis and biological properties of Tyr-D-Arg-Phe-βAla-NH2 and its fluorinated aromatic amino acid derivatives
Sasaki,Ambo,Suzuki
, p. 2316 - 2318 (2007/10/02)
Tyr-D-Arg-Phe-βAla-NH2 (I) and its six fluorinated analogs were synthesized. Their opioid receptor binding properties were examined in vitro and their analgesic activity in vivo using the mouse writhing test. It was found that I was one of the
