The CAS Registry Mumber 1856-28-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1856-28: (6*1)+(5*8)+(4*5)+(3*6)+(2*2)+(1*8)=96 96 % 10 = 6 So 1856-28-6 is a valid CAS Registry Number.
