AcidCheck Digit Verification of cas no
The CAS Registry Mumber 10143-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,4 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 10143-02:
(7*1)+(6*0)+(5*1)+(4*4)+(3*3)+(2*0)+(1*2)=39
39 % 10 = 9
So 10143-02-9 is a valid CAS Registry Number.
