Check Digit Verification of cas no
The CAS Registry Mumber 209908-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,9,0 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 209908-56:
(8*2)+(7*0)+(6*9)+(5*9)+(4*0)+(3*8)+(2*5)+(1*6)=155
155 % 10 = 5
So 209908-56-5 is a valid CAS Registry Number.
