Check Digit Verification of cas no
The CAS Registry Mumber 5421-66-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5421-66:
(6*5)+(5*4)+(4*2)+(3*1)+(2*6)+(1*6)=79
79 % 10 = 9
So 5421-66-9 is a valid CAS Registry Number.
