89490-60-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89490-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,9 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89490-60:
(7*8)+(6*9)+(5*4)+(4*9)+(3*0)+(2*6)+(1*0)=178
178 % 10 = 8
So 89490-60-8 is a valid CAS Registry Number.
