The CAS Registry Mumber 90364-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,6 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90364-55:
(7*9)+(6*0)+(5*3)+(4*6)+(3*4)+(2*5)+(1*5)=129
129 % 10 = 9
