Check Digit Verification of cas no
The CAS Registry Mumber 130944-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,4 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130944-51:
(8*1)+(7*3)+(6*0)+(5*9)+(4*4)+(3*4)+(2*5)+(1*1)=113
113 % 10 = 3
So 130944-51-3 is a valid CAS Registry Number.
