The CAS Registry Mumber 856-20-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 6 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 856-20: (5*8)+(4*5)+(3*6)+(2*2)+(1*0)=82 82 % 10 = 2 So 856-20-2 is a valid CAS Registry Number.
