The CAS Registry Mumber 23857-04-7 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, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 23857-04: (7*2)+(6*3)+(5*8)+(4*5)+(3*7)+(2*0)+(1*4)=117 117 % 10 = 7 So 23857-04-7 is a valid CAS Registry Number.
