The CAS Registry Mumber 74085-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 74085-70: (7*7)+(6*4)+(5*0)+(4*8)+(3*5)+(2*7)+(1*0)=134 134 % 10 = 4 So 74085-70-4 is a valid CAS Registry Number.
