Check Digit Verification of cas no
The CAS Registry Mumber 4013-24-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,1 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.Calculate Digit Verification of CAS Registry Number 4013-24:
(6*4)+(5*0)+(4*1)+(3*3)+(2*2)+(1*4)=45
45 % 10 = 5
So 4013-24-5 is a valid CAS Registry Number.
