Check Digit Verification of cas no
The CAS Registry Mumber 204906-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,0 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 204906-08:
(8*2)+(7*0)+(6*4)+(5*9)+(4*0)+(3*6)+(2*0)+(1*8)=111
111 % 10 = 1
So 204906-08-1 is a valid CAS Registry Number.
