89889-14-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89889-14-5 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 89889-14:
(7*8)+(6*9)+(5*8)+(4*8)+(3*9)+(2*1)+(1*4)=215
215 % 10 = 5
So 89889-14-5 is a valid CAS Registry Number.
