Check Digit Verification of cas no
The CAS Registry Mumber 206195-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,1,9 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 206195-05:
(8*2)+(7*0)+(6*6)+(5*1)+(4*9)+(3*5)+(2*0)+(1*5)=113
113 % 10 = 3
So 206195-05-3 is a valid CAS Registry Number.
