The CAS Registry Mumber 1204748-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,7,4 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1204748-41:
(9*1)+(8*2)+(7*0)+(6*4)+(5*7)+(4*4)+(3*8)+(2*4)+(1*1)=133
133 % 10 = 3
