The CAS Registry Mumber 3380-35-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,8 and 0 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3380-35: (6*3)+(5*3)+(4*8)+(3*0)+(2*3)+(1*5)=76 76 % 10 = 6 So 3380-35-6 is a valid CAS Registry Number.
