Check Digit Verification of cas no
The CAS Registry Mumber 104884-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,8 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104884-06:
(8*1)+(7*0)+(6*4)+(5*8)+(4*8)+(3*4)+(2*0)+(1*6)=122
122 % 10 = 2
So 104884-06-2 is a valid CAS Registry Number.
