83731-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83731-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83731-83:
(7*8)+(6*3)+(5*7)+(4*3)+(3*1)+(2*8)+(1*3)=143
143 % 10 = 3
So 83731-83-3 is a valid CAS Registry Number.

Enzymatic Synthesis of Dynorphin (1-8)
Kullmann, Willi
, p. 5300 - 5303 (2007/10/02)
Conventional syntheses of arginyl peptides are often accompanied by undesired side reactions.An alternative approach is proposed to overcome these difficulties which exploits the proteosynthetic potential of trypsin.The enzyme's specificity ensures regio-
