The CAS Registry Mumber 1915-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 5 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1915-45: (6*1)+(5*9)+(4*1)+(3*5)+(2*4)+(1*5)=83 83 % 10 = 3 So 1915-45-3 is a valid CAS Registry Number.
