89552-73-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89552-73-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89552-73:
(7*8)+(6*9)+(5*5)+(4*5)+(3*2)+(2*7)+(1*3)=178
178 % 10 = 8
So 89552-73-8 is a valid CAS Registry Number.
