The CAS Registry Mumber 2939-03-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,3 and 9 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2939-03: (6*2)+(5*9)+(4*3)+(3*9)+(2*0)+(1*3)=99 99 % 10 = 9 So 2939-03-9 is a valid CAS Registry Number.
