The CAS Registry Mumber 289900-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,0 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 289900-01:
(8*2)+(7*8)+(6*9)+(5*9)+(4*0)+(3*0)+(2*0)+(1*1)=172
172 % 10 = 2
So 289900-01-2 is a valid CAS Registry Number.
