Check Digit Verification of cas no
The CAS Registry Mumber 905449-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,4,4 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 905449-88:
(8*9)+(7*0)+(6*5)+(5*4)+(4*4)+(3*9)+(2*8)+(1*8)=189
189 % 10 = 9
So 905449-88-9 is a valid CAS Registry Number.
