The CAS Registry Mumber 474688-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,6,8 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 474688-81:
(8*4)+(7*7)+(6*4)+(5*6)+(4*8)+(3*8)+(2*8)+(1*1)=208
208 % 10 = 8
So 474688-81-8 is a valid CAS Registry Number.
