89889-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89889-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,8 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89889-18:
(7*8)+(6*9)+(5*8)+(4*8)+(3*9)+(2*1)+(1*8)=219
219 % 10 = 9
So 89889-18-9 is a valid CAS Registry Number.
