The CAS Registry Mumber 6861-48-9 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 1 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6861-48: (6*6)+(5*8)+(4*6)+(3*1)+(2*4)+(1*8)=119 119 % 10 = 9 So 6861-48-9 is a valid CAS Registry Number.
