The CAS Registry Mumber 400758-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,5 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 400758-66:
(8*4)+(7*0)+(6*0)+(5*7)+(4*5)+(3*8)+(2*6)+(1*6)=129
129 % 10 = 9
So 400758-66-9 is a valid CAS Registry Number.
