4-5Check Digit Verification of cas no
The CAS Registry Mumber 6227-17-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.Calculate Digit Verification of CAS Registry Number 6227-17:
(6*6)+(5*2)+(4*2)+(3*7)+(2*1)+(1*7)=84
84 % 10 = 4
So 6227-17-4 is a valid CAS Registry Number.
