The CAS Registry Mumber 130251-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,5 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130251-35:
(8*1)+(7*3)+(6*0)+(5*2)+(4*5)+(3*1)+(2*3)+(1*5)=73
73 % 10 = 3
So 130251-35-3 is a valid CAS Registry Number.
