The CAS Registry Mumber 6871-71-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,7 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6871-71:
(6*6)+(5*8)+(4*7)+(3*1)+(2*7)+(1*1)=122
122 % 10 = 2
So 6871-71-2 is a valid CAS Registry Number.
