The CAS Registry Mumber 23857-31-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,8,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 23857-31: (7*2)+(6*3)+(5*8)+(4*5)+(3*7)+(2*3)+(1*1)=120 120 % 10 = 0 So 23857-31-0 is a valid CAS Registry Number.
