The CAS Registry Mumber 89919-51-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,1 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89919-51:
(7*8)+(6*9)+(5*9)+(4*1)+(3*9)+(2*5)+(1*1)=197
197 % 10 = 7
So 89919-51-7 is a valid CAS Registry Number.
