Check Digit Verification of cas no
The CAS Registry Mumber 289505-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,5,0 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 289505-15:
(8*2)+(7*8)+(6*9)+(5*5)+(4*0)+(3*5)+(2*1)+(1*5)=173
173 % 10 = 3
So 289505-15-3 is a valid CAS Registry Number.
