Check Digit Verification of cas no
The CAS Registry Mumber 104689-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104689-08:
(8*1)+(7*0)+(6*4)+(5*6)+(4*8)+(3*9)+(2*0)+(1*8)=129
129 % 10 = 9
So 104689-08-9 is a valid CAS Registry Number.
