Check Digit Verification of cas no
The CAS Registry Mumber 108409-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,4,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108409-76:
(8*1)+(7*0)+(6*8)+(5*4)+(4*0)+(3*9)+(2*7)+(1*6)=123
123 % 10 = 3
So 108409-76-3 is a valid CAS Registry Number.
