The CAS Registry Mumber 90295-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,9 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90295-69:
(7*9)+(6*0)+(5*2)+(4*9)+(3*5)+(2*6)+(1*9)=145
145 % 10 = 5
So 90295-69-5 is a valid CAS Registry Number.
