The CAS Registry Mumber 904915-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,9,1 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 904915-03:
(8*9)+(7*0)+(6*4)+(5*9)+(4*1)+(3*5)+(2*0)+(1*3)=163
163 % 10 = 3
So 904915-03-3 is a valid CAS Registry Number.
