191223-09-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191223-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,2,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 191223-09:
(8*1)+(7*9)+(6*1)+(5*2)+(4*2)+(3*3)+(2*0)+(1*9)=113
113 % 10 = 3
So 191223-09-3 is a valid CAS Registry Number.

N-crotonoyl derivatives of oligopeptides and their copolymers with N-vinylpyrrolidone
Nazarov,Panarin
, p. 132 - 134 (2007/10/03)
A series of N-crotonoyl derivatives of oligopeptides are prepared. The possibility of preparing their water-soluble copolymers with N-vinylpyrrolidone, characterized by narrow molecular-weight distribution, is examined.
