The CAS Registry Mumber 7615-03-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,1 and 5 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 7615-03: (6*7)+(5*6)+(4*1)+(3*5)+(2*0)+(1*3)=94 94 % 10 = 4 So 7615-03-4 is a valid CAS Registry Number.
