89546-52-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89546-52-1 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 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89546-52:
(7*8)+(6*9)+(5*5)+(4*4)+(3*6)+(2*5)+(1*2)=181
181 % 10 = 1
So 89546-52-1 is a valid CAS Registry Number.
