Check Digit Verification of cas no
The CAS Registry Mumber 227456-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,4,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 227456-28:
(8*2)+(7*2)+(6*7)+(5*4)+(4*5)+(3*6)+(2*2)+(1*8)=142
142 % 10 = 2
So 227456-28-2 is a valid CAS Registry Number.
