Check Digit Verification of cas no
The CAS Registry Mumber 6259-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6259-66:
(6*6)+(5*2)+(4*5)+(3*9)+(2*6)+(1*6)=111
111 % 10 = 1
So 6259-66-1 is a valid CAS Registry Number.
