The CAS Registry Mumber 1273048-03-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,0,4 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1273048-03:
(9*1)+(8*2)+(7*7)+(6*3)+(5*0)+(4*4)+(3*8)+(2*0)+(1*3)=135
