403804-41-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403804-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,8,0 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 403804-41:
(8*4)+(7*0)+(6*3)+(5*8)+(4*0)+(3*4)+(2*4)+(1*1)=111
111 % 10 = 1
So 403804-41-1 is a valid CAS Registry Number.

Cysteine derivatives as inhibitors for carboxypeptidase A: Synthesis and structure-activity relationships
Park, Jung Dae,Kim, Dong H.
, p. 911 - 918 (2002)
A series of cysteine (Cys) derivatives having an alkyl or arylalkyl moiety on the α-amino group of the amino acid have been synthesized as a novel type of inhibitor for carboxypeptidase A. These compounds are readily prepared starting with Cys in an optic
