The CAS Registry Mumber 6931-68-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6931-68: (6*6)+(5*9)+(4*3)+(3*1)+(2*6)+(1*8)=116 116 % 10 = 6 So 6931-68-6 is a valid CAS Registry Number.
