Check Digit Verification of cas no
The CAS Registry Mumber 20809-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20809-78:
(7*2)+(6*0)+(5*8)+(4*0)+(3*9)+(2*7)+(1*8)=103
103 % 10 = 3
So 20809-78-3 is a valid CAS Registry Number.
