89152-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89152-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,5 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89152-20:
(7*8)+(6*9)+(5*1)+(4*5)+(3*2)+(2*2)+(1*0)=145
145 % 10 = 5
So 89152-20-5 is a valid CAS Registry Number.
