62489-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62489-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,8 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 62489-09:
(7*6)+(6*2)+(5*4)+(4*8)+(3*9)+(2*0)+(1*9)=142
142 % 10 = 2
So 62489-09-2 is a valid CAS Registry Number.
