89019-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89019-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,1 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89019-87:
(7*8)+(6*9)+(5*0)+(4*1)+(3*9)+(2*8)+(1*7)=164
164 % 10 = 4
So 89019-87-4 is a valid CAS Registry Number.
