The CAS Registry Mumber 90904-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,0 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90904-26:
(7*9)+(6*0)+(5*9)+(4*0)+(3*4)+(2*2)+(1*6)=130
130 % 10 = 0
So 90904-26-0 is a valid CAS Registry Number.
