The CAS Registry Mumber 662-19-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 2 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 662-19: (5*6)+(4*6)+(3*2)+(2*1)+(1*9)=71 71 % 10 = 1 So 662-19-1 is a valid CAS Registry Number.
