The CAS Registry Mumber 71657-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 71657-70: (7*7)+(6*1)+(5*6)+(4*5)+(3*7)+(2*7)+(1*0)=140 140 % 10 = 0 So 71657-70-0 is a valid CAS Registry Number.
