The CAS Registry Mumber 28850-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,5 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28850-17:
(7*2)+(6*8)+(5*8)+(4*5)+(3*0)+(2*1)+(1*7)=131
131 % 10 = 1
So 28850-17-1 is a valid CAS Registry Number.
