The CAS Registry Mumber 91990-87-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91990-87:
(7*9)+(6*1)+(5*9)+(4*9)+(3*0)+(2*8)+(1*7)=173
173 % 10 = 3
So 91990-87-3 is a valid CAS Registry Number.
