The CAS Registry Mumber 674-11-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 4 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 674-11: (5*6)+(4*7)+(3*4)+(2*1)+(1*1)=73 73 % 10 = 3 So 674-11-3 is a valid CAS Registry Number.
