Check Digit Verification of cas no
The CAS Registry Mumber 22250-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,5 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22250-99:
(7*2)+(6*2)+(5*2)+(4*5)+(3*0)+(2*9)+(1*9)=83
83 % 10 = 3
So 22250-99-3 is a valid CAS Registry Number.
