1143-02-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1143-02-8 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, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1143-02:
(6*1)+(5*1)+(4*4)+(3*3)+(2*0)+(1*2)=38
38 % 10 = 8
So 1143-02-8 is a valid CAS Registry Number.
