Check Digit Verification of cas no
The CAS Registry Mumber 450-90-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 450-90:
(5*4)+(4*5)+(3*0)+(2*9)+(1*0)=58
58 % 10 = 8
So 450-90-8 is a valid CAS Registry Number.
