The CAS Registry Mumber 6704-30-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,0 and 4 respectively; the second part has 2 digits, 3 and 0 respectively. Calculate Digit Verification of CAS Registry Number 6704-30: (6*6)+(5*7)+(4*0)+(3*4)+(2*3)+(1*0)=89 89 % 10 = 9 So 6704-30-9 is a valid CAS Registry Number.
