The CAS Registry Mumber 3603-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,0 and 3 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3603-78: (6*3)+(5*6)+(4*0)+(3*3)+(2*7)+(1*8)=79 79 % 10 = 9 So 3603-78-9 is a valid CAS Registry Number.
