Check Digit Verification of cas no
The CAS Registry Mumber 225221-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,2,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 225221-85:
(8*2)+(7*2)+(6*5)+(5*2)+(4*2)+(3*1)+(2*8)+(1*5)=102
102 % 10 = 2
So 225221-85-2 is a valid CAS Registry Number.
