89448-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89448-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,4 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89448-53:
(7*8)+(6*9)+(5*4)+(4*4)+(3*8)+(2*5)+(1*3)=183
183 % 10 = 3
So 89448-53-3 is a valid CAS Registry Number.
