The CAS Registry Mumber 311348-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,3,4 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 311348-69:
(8*3)+(7*1)+(6*1)+(5*3)+(4*4)+(3*8)+(2*6)+(1*9)=113
113 % 10 = 3
So 311348-69-3 is a valid CAS Registry Number.
