85197-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85197-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,9 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85197-97:
(7*8)+(6*5)+(5*1)+(4*9)+(3*7)+(2*9)+(1*7)=173
173 % 10 = 3
So 85197-97-3 is a valid CAS Registry Number.
