The CAS Registry Mumber 3430-48-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,3 and 0 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3430-48: (6*3)+(5*4)+(4*3)+(3*0)+(2*4)+(1*8)=66 66 % 10 = 6 So 3430-48-6 is a valid CAS Registry Number.
