The CAS Registry Mumber 67213-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67213-22:
(7*6)+(6*7)+(5*2)+(4*1)+(3*3)+(2*2)+(1*2)=113
113 % 10 = 3
So 67213-22-3 is a valid CAS Registry Number.
