The CAS Registry Mumber 28750-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,5 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.Calculate Digit Verification of CAS Registry Number 28750-51:
(7*2)+(6*8)+(5*7)+(4*5)+(3*0)+(2*5)+(1*1)=128
128 % 10 = 8
So 28750-51-8 is a valid CAS Registry Number.
