The CAS Registry Mumber 793-64-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 3 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 793-64: (5*7)+(4*9)+(3*3)+(2*6)+(1*4)=96 96 % 10 = 6 So 793-64-6 is a valid CAS Registry Number.
