The CAS Registry Mumber 3702-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3702-20: (6*3)+(5*7)+(4*0)+(3*2)+(2*2)+(1*0)=63 63 % 10 = 3 So 3702-20-3 is a valid CAS Registry Number.
