The CAS Registry Mumber 1260633-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,6,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1260633-71:
(9*1)+(8*2)+(7*6)+(6*0)+(5*6)+(4*3)+(3*3)+(2*7)+(1*1)=133
133 % 10 = 3
So 1260633-71-3 is a valid CAS Registry Number.
