Check Digit Verification of cas no
The CAS Registry Mumber 208453-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,5 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 208453-17:
(8*2)+(7*0)+(6*8)+(5*4)+(4*5)+(3*3)+(2*1)+(1*7)=122
122 % 10 = 2
So 208453-17-2 is a valid CAS Registry Number.
