The CAS Registry Mumber 3245-98-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 5 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3245-98: (6*3)+(5*2)+(4*4)+(3*5)+(2*9)+(1*8)=85 85 % 10 = 5 So 3245-98-5 is a valid CAS Registry Number.
