The CAS Registry Mumber 6919-49-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6919-49: (6*6)+(5*9)+(4*1)+(3*9)+(2*4)+(1*9)=129 129 % 10 = 9 So 6919-49-9 is a valid CAS Registry Number.
