The CAS Registry Mumber 80866-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,6 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80866-50:
(7*8)+(6*0)+(5*8)+(4*6)+(3*6)+(2*5)+(1*0)=148
148 % 10 = 8
So 80866-50-8 is a valid CAS Registry Number.
