The CAS Registry Mumber 6226-77-3 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 6 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 6226-77:
(6*6)+(5*2)+(4*2)+(3*6)+(2*7)+(1*7)=93
93 % 10 = 3
So 6226-77-3 is a valid CAS Registry Number.
