The CAS Registry Mumber 6860-76-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,6 and 0 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6860-76: (6*6)+(5*8)+(4*6)+(3*0)+(2*7)+(1*6)=120 120 % 10 = 0 So 6860-76-0 is a valid CAS Registry Number.
