The CAS Registry Mumber 81291-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,9 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81291-90:
(7*8)+(6*1)+(5*2)+(4*9)+(3*1)+(2*9)+(1*0)=129
129 % 10 = 9
So 81291-90-9 is a valid CAS Registry Number.
