Check Digit Verification of cas no
The CAS Registry Mumber 144403-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144403-63:
(8*1)+(7*4)+(6*4)+(5*4)+(4*0)+(3*3)+(2*6)+(1*3)=104
104 % 10 = 4
So 144403-63-4 is a valid CAS Registry Number.
