Check Digit Verification of cas no
The CAS Registry Mumber 205517-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,1 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205517-80:
(8*2)+(7*0)+(6*5)+(5*5)+(4*1)+(3*7)+(2*8)+(1*0)=112
112 % 10 = 2
So 205517-80-2 is a valid CAS Registry Number.
