89543-00-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89543-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,4 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89543-00:
(7*8)+(6*9)+(5*5)+(4*4)+(3*3)+(2*0)+(1*0)=160
160 % 10 = 0
So 89543-00-0 is a valid CAS Registry Number.
