89434-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89434-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89434-34:
(7*8)+(6*9)+(5*4)+(4*3)+(3*4)+(2*3)+(1*4)=164
164 % 10 = 4
So 89434-34-4 is a valid CAS Registry Number.

S-oxidation and anticoagulant activity of thio analogues of phenprocoumon
Rehse,Ruther
, p. 103 - 107 (2007/10/02)
Methylthio and butylthio compounds analogous to phenprocoumon and their sulfinyl and sulfonyl derivatives were synthesized. The anticoagulant activity of the methylthio compound 3a is equal to that of the lead compound. The butylthio compound 3b reaches o
