89864-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89864-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,6 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89864-45:
(7*8)+(6*9)+(5*8)+(4*6)+(3*4)+(2*4)+(1*5)=199
199 % 10 = 9
So 89864-45-9 is a valid CAS Registry Number.
