Check Digit Verification of cas no
The CAS Registry Mumber 1143-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1143-74:
(6*1)+(5*1)+(4*4)+(3*3)+(2*7)+(1*4)=54
54 % 10 = 4
So 1143-74-4 is a valid CAS Registry Number.
