Check Digit Verification of cas no
The CAS Registry Mumber 1443227-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,2,2 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1443227-31:
(9*1)+(8*4)+(7*4)+(6*3)+(5*2)+(4*2)+(3*7)+(2*3)+(1*1)=133
133 % 10 = 3
So 1443227-31-3 is a valid CAS Registry Number.
