Check Digit Verification of cas no
The CAS Registry Mumber 6227-20-9 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, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6227-20:
(6*6)+(5*2)+(4*2)+(3*7)+(2*2)+(1*0)=79
79 % 10 = 9
So 6227-20-9 is a valid CAS Registry Number.
