The CAS Registry Mumber 186000-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,0,0 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 186000-66:
(8*1)+(7*8)+(6*6)+(5*0)+(4*0)+(3*0)+(2*6)+(1*6)=118
118 % 10 = 8
So 186000-66-8 is a valid CAS Registry Number.
