Check Digit Verification of cas no
The CAS Registry Mumber 125989-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,8 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125989-73:
(8*1)+(7*2)+(6*5)+(5*9)+(4*8)+(3*9)+(2*7)+(1*3)=173
173 % 10 = 3
